We observe two transitions, at temperatures T* and T-c in this pelletized sample. We identify the lower temperature transition T* with the onset of intergranular shielding currents. The upper transition temperature T,(P) falls on a universal T-c(P) curve, defined from similar data obtained previously on K3C60 and Rb3C60, after we shift the pressure axis for our data by -2.6 kbars. We identify T-c as a superconducting transition in Rb2CsC60 on the basis of the compressibility analysis and published values of the lattice parameters for alkali-doped C-60, as well as T-c(P = 0) and (dT(c)/dP)(p=0).

In particular, the effect of density fluctuations between these one- or two-dimensional coupled layers on intralayer phase separation and pairing is analyzed. The most robust signals of superconductivity are found at quarter filling for couplings just before the fully interlayer phase separated regime. The possibility of an enhancement of the intralayer superconducting pairing correlations by the interlayer couplings is investigated. C1 VANDERBILT UNIV,DEPT PHYS & ASTRON,NASHVILLE,TN 37235.

Strong nonadiabaticity, when it is impossible, strictly speaking, to separate fully the nuclear and electronic degrees of freedom, leads to a peculiar dependence of the carrier concentration n on the ionic mass M. This case corresponds, for example, to the isotopic substitution of the axial oxygen in YBa2Cu3O7-x. Because of the dependence of T-c on n, this leads to the dependence of T-c on M, that is to the isotope effect. The minimum value of the isotope coefficient corresponds to T-c=T-c(max).

The phases of the spinon and holon order parameters couple gauge invariantly via a statistical gauge field, which arises from the implicit strong interaction physics. We find that physical electronic phase correlations show a superconductor-normal-metal phase transition of the Berezinskii-Kosterlitz-Thouless type, while statistical gauge-field excitations are strictly gapless. These results are discussed in the context of both the superconducting and the normal-state properties of the oxide superconductors. C1 LOS ALAMOS NATL LAB,DIV THEORY,LOS ALAMOS,NM 87545.

Tunneling data follow the general trend of the best curves seen in cuprate high-temperature superconductors, but these show significantly lower and flatter subgap conductance values than any other cuprate and they can be reproducibly obtained. By fitting the data to a smeared BCS density of states, the energy gap has been determined and the smearing parameter is so small that it is comparable to thermal smearing.

By employing the electron partial-yield detection technique, spectra of NaF, NaCl, and NaBr were obtained near the sodium K edge and spectra of LiF, NaF, and KF were obtained near the fluorine K edge. All spectra showed sharp absorption features at the absorption threshold and broader features extending 50-80 eV above threshold. Some narrow features close to threshold are attributed to core-level excitons. Contributions from atomic multiple-electron excitations, estimated by a comparison to the K-edge photoabsorption spectrum of Ne in the gas phase, are found to be very small. Thus, the intense broader peaks observed further above threshold arise from single-electron scattering resonances. These highly structured spectra of well-characterized ordered crystals provide a set of standard data which is used to test the multiple-scattering x-ray-absorption code FEFF V. For some spectra, at photon energies more than almost-equal-to 10 eV above threshold, the calculations achieve very good agreement with experiment. The dependence of the calculation on cluster size, order of scattering, and choice of self-energy is demonstrated. C1 LAWRENCE BERKELEY LAB,DIV CHEM SCI,BERKELEY,CA 94720.

It is found that the Au L3,2-edge XANES of AuZn exhibits a noticeable white line at the absorption threshold indicating 5d electron depletion at the Au site in AuZn. Analysis of the area under the white line yields a depletion of 0.052 5d electron at the Au site in AuZn relative to Au metal, in qualitative agreement with the charge compensation model analysis using x-ray photoelectron spectroscopy and Mossbauer data. The latter shows a 5d depletion count of 0.14 electron. The implication of these analyses is discussed. C1 UNIV WESTERN ONTARIO,DEPT CHEM,LONDON N6A 5B7,ONTARIO,CANADA.

X-ray measurements were performed by energy dispersive diffraction with synchrotron radiation. Monatomic metallic iodine transforms to an fcc structure at 53 GPa that remains stable to the maximum pressure. At 276 GPa, the volume compression V/V0 is 0.324. Reflectivity data are consistent with a strong metallic character in iodine from 19 to 181 GPa. The linear muffin-tin orbital method has been used to calculate the equation of state to 500 GPa and to model the reflectivity of iodine at high pressures.

Some of the short-range order is taken into account by considering a coated sphere as the basic scattering unit. A generalization of the energy-transport velocity is obtained. The validity of our approach is checked by comparison with experimental results, as well as with numerical calculations. Results for the long-wavelength effective dielectric constant, phase velocity, energy-transport velocity, mean free path, and diffusion coefficient are presented and compared with experiments on scattering from dielectric spheres. In addition, our findings suggest that the positions of the band gaps in periodic dielectric structures are closely related with the range of localized states in random dielectric media.

Pr0.5Ca0.5Ba2Cu3O7-delta epitaxial thin films exhibit a superconducting onset temperature as high as 47 K with T(c)(R = 0) = 35 K. X-ray-diffraction and electrical-transport data suggest that Ca doping levels greater than x = 0.5 are possible, although disorder is introduced as the divalent to trivalent cation ratio becomes large. This work demonstrates that 1:2:3-phase superconductivity can be achieved by substituting Ca for Pr, without the presence in the alloy of Y or any other rare-earth element, R, for which RBa2Cu3O7-delta is superconducting. This result supports the view that hole localization, due to hybridization of the Pr 4f electronic levels with the O 2p orbitals, contributes substantially to the suppression of superconductivity by Pr in PrBa2Cu3O7-delta, and demonstrates that this suppression can be partially compensated by appropriate hole doping with Ca.

The system is described by a Su-Schrieffer-Heeger Hubbard-type Hamiltonian which is solved perturbatively in the electron-electron interactions. The optical-absorption spectrum is computed including both the direct and one-phonon-induced processes. Electronic-correlation effects are qualitatively important and, if and only if the electron-electron interaction is taken to be large enough, good agreement with experiments is achieved. Furthermore, it is shown that, in this model, the lowest-energy spin-triplet state is stable against decay due to a large Coulomb binding. Also, the theory predicts a triplet-triplet band about at 0.45 eV which, to my knowledge, has not yet been observed experimentally.

The A00NN are qualitatively described by recent phase shift analyses, but a quantitative shape and normalization discrepancy remains in the forward angle region. These new data provide important constraints for nucleon-nucleon spin-dependent amplitudes at forward angles which are used in theoretical models of nucleon-nucleus scattering.

The alternating-parity sequences already observed up to I = 31/2 do not seem to develop further at higher spins. A new sideband was observed as well as several E2/Ml transitions linking the states of positive parity. Multipolarities and mixing ratios were deduced from an analysis of DCO ratios. In addition mixing ratios were obtained independently from the branching ratios. This allowed for determination of B(M1)/B(E2) ratios up to I(pi) = 29/2+. The data are discussed in terms of a transition from the weak coupling scheme at low and medium spins to the particle-hole regime for I greater than or similar to 31/2.

In the resonance and the intermediate resonance region, very little of the previously reported structure was detected. Only five resonance structures were observed. Additionally, the width of the 5.45 eV resonance is approximately 100 times smaller than previously reported. An explanation for the discrepancies between old data and data reported here is discussed. New fission widths for resonances from 5.45 eV to 10.4 keV are reported. The new data are in agreement with theoretical estimates. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545. OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

We determine a range of values for the suppression of proton emission from this state for which the two measurements of strength are consistent. Recent studies of this state support this suppression and the amount of suppression is within our allowed range. Using the experimentally determined value for the suppression we are able to determine neutrino cross sections on Cl-37 from B-8 solar neutrinos, supernova neutrinos, and mu+ decay neutrinos. Our cross section for mu+ decay neutrinos is found to be 20% larger than the estimates of Bahcall, because of high-lying strength only recently confirmed by the Ca-37 beta+ decay experiment.

Two weakly populated rotational bands have been observed with properties (energy spacings and dynamic moments of inertia) very similar to those of other superdeformed bands in the A approximately 190 region. The two bands can be interpreted as signature partners which exhibit some signature splitting for rotational frequencies HomegaBAR greater-than-or 0.2 MeV. They are interpreted within the framework of cranked Woods-Saxon calculations as being based on the proton i13/2(OMEGA=5/2) intruder orbital, in agreement with pairs of superdeformed bands seen in neighboring odd TI nuclei.

The distorted-wave impulse approximation formulated in momentum space is used to calculate the cross sections of (pi, pi') and (gamma, pi) reactions from the piN --> piN and piN --> gammaN off-shell amplitudes which are generated from the model of Nozawa, Blankleider, and Lee [Nucl. Phys. A513, 459 (1990)]. It is found that the nonlocal effects due to piN off-shell dynamics and nucleon Fermi motion are important in predicting (gamma, pi) cross sections. The one-pion-exchange two-body exchange currents are included in (e, e') calculations. It is shown that the core polarization effects, calculated in a perturbation approach including excitations up to 6HomegaBAR, are essential in obtaining quantitative agreements with the data with no adjustable parameters. The predictions based on the shell model of Cohen and Kurath [Nucl. Phys. 73, 1 (1965)] and Hague and Maripuu [Phys. Rev. C 8, 1609 (1973)] are compared in order to illustrate the use of (e, e'), (pi, pi'), and (gamma, pi) reactions in distinguishing nuclear structure theories which are almost equivalent in describing static properties of nuclei. Predictions for future (e, e') and (gamma, pi) experiments are also presented. C1 ARGONNE NATL LAB,DEPT PHYS,ARGONNE,IL 60439.

The results for O-16 are compared with those obtained using effective interactions and the random-phase approximation. The responses of H-2 and the Laplace transforms of the responses of H-2 and He-4 are also calculated. We confirm the earlier predictions that nuclear forces enhance the isovector spin-longitudinal response over the spin-transverse. However, we find that they also push the strength of both these responses to higher energies. Indications of the predicted enhancement have not been observed in p over arrow pointing right, n over arrow pointing right experiments on C-12 and Ca-40 recently carried out at Los Alamos. We find that conventional nuclear theory predicts a measurable enhancement in H-2 and a significant enhancement in He-4. Since many properties of these few-body nuclei are well explained with realistic nuclear forces an experimental verification of the enhancement, or its absence, in H-2 and He-4 will be very interesting.

Evidence is presented for a selective population of states in Si-28 fragments arising from the symmetric fission of the Ni-56 compound nucleus. A statistical-model calculation of the expected strength to specific mutual excitations of the fission fragments is presented and compared to the experimental results. This calculation is found to describe the structures observed at high excitation energy in the fission Q-value spectra quite well. Analysis of the gamma-ray spectra indicates, however, that a specific set of states in Si-28, corresponding to a highly deformed prolate band, is populated more strongly than expected based on a purely spin-weighted, statistical decay of the compound nucleus. It is suggested that the population pattern of states in the fission fragments may reflect nuclear structure effects at the point of scission. C1 ARGONNE NATL LAB,ARGONNE,IL 60439.

High-resolution Q-value spectra have been obtained for the large-angle yields in the Mg-24+Mg-24 and Ne-20+Si-28 channels. Calculations based on the transition-state model are found to reproduce the fully damped cross sections in all of the observed mass channels. The pronounced structure that is observed in the excitation-energy spectra for the more symmetric mass channels, even for the strongly damped yields, is shown to be qualitatively reproduced by assuming a spin-weighted population of the fragment states. There is also evidence, however, that the structure of the nascent fission fragments at scission may influence the population of states in the fragments. These results, taken together with earlier measurements of the resonance behavior of this system, suggest the coexistence of fission from the normal, compact compound nucleus with that from the deformed configurations believed to be responsible for the resonance behavior.

The low energy I=0 and I=1 S-wave KN phase shifts are in reasonably good agreement with experiment given conventional quark model parameters. For k(lab) > 0.7 GeV, however, the I=1 elastic phase shift is larger than predicted by Gaussian wave functions, and we suggest possible reasons for this discrepancy. Equivalent low energy KN potentials for S-wave scattering are also derived. Finally we consider OGE forces in the related channels KDELTA, K*N, and K*DELTA, and determine which have attractive interactions and might therefore exhibit strong threshold enhancements or ''Z*-molecule'' meson-baryon bound states. We find that the minimum-spin, minimum-isospin channels and two additional K*DELTA channels are most conducive to the formation of bound states. Related interesting topics for future experimental and theoretical studies of KN interactions are also discussed. C1 OAK RIDGE NATL LAB,CTR COMPUTAT INTENS PHYS,OAK RIDGE,TN 37831.

These nuclei were produced in the fusion reaction 250 MeV Ni-60 + Mo-100. In general the nuclear decays are too fast to be timed by this clock, however, alpha-particle emitting compound nucleus states have lifetimes sufficiently long for this technique to work when both the alpha-particle has low energy and the compound nucleus spin is large. This supports the existence of last, or near last, chance alpha-particle emission in the deexcitation of high spin compound nuclei. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

In addition, states up to I(pi)=(22+) have been seen in 78Sr. The alpha=1/2, g9/2 band and both signature partners of the negative parity band in 77Sr were found to be identical to the yrast band in 78Sr with relative alignments of 1.22(7)HBAR, 0.52(5)HBAR (alpha=1/2), and 0.42(4)HBAR (alpha=-1/2), respectively. In one of the negative parity bands, the identicality persists through the first proton band crossing. The odd spin decay sequence of the 4- band in 78Rb is identical to the ground band of 78Sr [3.02(3)HBAR] at low spin and to the alpha=1/2, g9/2 band in 77Rb [1.11(3)HBAR] at higher spins. These are the only known examples of identical bands in the neutron deficient A=80 region. The analysis indicates that the [301]3/2 Nilsson orbital is a very good spectator orbital.

The uncertainty principle is used to relate the lifetime of a radiating parton to its virtuality and momentum. The interaction time of each hard or semihard parton scattering is also taken into account. For central Au+Au collisions at root s = 200 GeV, most of the partons are found to be produced within 0.5 fm/c after the total overlap of the two colliding nuclei. The local momentum distribution is approximately isotropical at that time. The implication on how to treat correctly the secondary scattering in an ultimate parton cascading model is also discussed.

We find that radiative corrections of order alpha(s), are very important. Over the kinematic range accessible in semileptonic decays, xi 3(v.v') is proportional to the leading-order Isgur-Wise function xi(v.v') to very good accuracy. Taking into account all sources of uncertainty we estimate xi 3/xi=(0.6+/-0.2). This reduces the theoretical uncertainty in the extraction of /V-cb/ from (B) over bar --> D l <(nu)over bar> transitions. A measurement of the form factor ratio A(2)/A(1) in <(B) over bar> --> D* l <(nu)over bar> decays can be used to test our prediction.

It is shown that the 10 x 10 anomalous dimension matrix, which describes the scale dependence of the dimension-four effective current operators in the heavy quark effective theory, is to a large extent determined by the equations of motion, heavy quark symmetry, and reparametrization invariance. The next-to-leading order expressions for the Wilson coefficients at order 1/m(Q) depend on only five unknown two-loop anomalous dimensions, among them that of the chromomagnetic operator.

We evaluate the gluon propagator both in time at zero three-momentum and in momentum space. From the former quantity we obtain evidence for a dynamically generated effective mass, which at beta=6.0 and beta=6.3 increases with the time separation of the sources, in agreement with earlier results. The momentum space propagator G(k) provides further evidence for mass generation. In particular, at beta=6.0, for 300 MeV less than or similar to k less than or similar to 1 GeV, the propagator G(k) can be fit to a continuum formula proposed by Gribov and others, which contains a mass scale b, presumably related to the hadronization mass scale. For higher momenta Gribov's model no longer provides a good fit, as G(k) tends rather to follow an inverse power law approximate to 1/k(2+gamma). The results at beta=6.3 are consistent with those at beta=6.0, but only the high momentum region is accessible on this lattice. We find b in the range of 300 to 400 MeV and gamma about 0.7. Fits to particle + ghost expressions are also possible, often resulting in low values for chi(DF)(2), but the parameters are very poorly determined. On the other hand, at beta=5.7 (where we can only study momenta up to 1 GeV) G(k) is best fit to a simple massive boson propagator with mass m. We argue that such a discrepancy may be related to a lack of scaling for low momenta at beta=5.7. From our results, the study of correlation functions in momentum space looks promising, especially because the data points in Fourier space turn out to be much less correlated than in real space.

It includes local and global bifurcations of regular and chaotic attractors. The bifurcations are classified according to the continuity or discontinuity of the attractor path, which governs the physical outcome that would be observed under a slow control sweep. Related issues of determinacy, hysteresis, basin structure, and intermittency are addressed. Recently discovered chaotic bifurcations are discussed in some detail, with particular reference to the regular or chaotic saddle-type destroyer with which an attractor may collide.

In terms of equivalent interface models, the family interpolates between the low-noise Ising (k = 1) and Toom (k = infinity) interfaces on a square lattice. Since the continuum description of density (or height) fluctuations in these models involves at most (k + 1)th-order terms in a gradient expansion, we can test specific renormalization-group predictions using Monte Carlo methods to probe scaling behavior. In particular we confirm the existence of multiplicative logarithms in the temporal behavior of mean-squared height fluctuations [approximately t1/2(ln t)1/4], induced by a marginal cubic gradient term. Analogs of redundant operators, familiar in the context of equilibrium systems, also appear to occur in these nonequilibrium systems. C1 BROOKHAVEN NATL LAB, DEPT PHYS, UPTON, NY 11973 USA.

The combination of the electron cooling and transverse-field modulation on the synchrotron oscillation is equivalent to a dissipative parametric resonant system. Six-dimensional Poincare maps were measured at ten-turn intervals. The proton bunch was observed to split longitudinally into two pieces, or beamlets, converging toward attractors of the dissipative system within a rf bucket. Based on our experimental results, the effects of ground vibration on the superconducting supercollider beam and the effects of power-supply ripple on the relativistic heavy-ion collider beam are examined.

We show numerically that two solitons in the system attract each other if the initial distance between them is smaller than a certain critical value; consequently, they will either form an oscillatory bound state with a finite lifetime, collapse to a stable single soliton state, or decay to the rotating background. If the initial separation is greater than the critical value, they separate to form a stable bound state at a second critical distance. The critical distances are in good agreement with the analytical prediction. C1 LOS ALAMOS NATL LAB,CTR NONLINEAR STUDIES,LOS ALAMOS,NM 87545.

The method is based on a graphical representation of global cellular-automata mappings. For a given cellular-automaton rule the recursive algorithm defines the change of the global cellular-automaton mapping as the number of lattice sites is incremented. A proof of lattice size invariance of global cellular-automata mappings is derived from an approximation to the exact recursive definition. The recursive definitions are applied to calculate the fractal dimension of the set of reachable states and of the set of fixed points of cellular automata on an infinite lattice.

This concept motivates a new ''conditional scaling'' method for analyzing measured instantaneous profiles or images of motion or scalar mixing in turbulent shear flow, involving the reparametrization of each profile or image so as to separate the distinct effects of large-scale and small-scale motions. The method, applied to species concentration profiles measured in a round jet, is found to capture profile shape features that are visually apparent in the instantaneous profiles but are not preserved by other conditioning methods. Similarity hypotheses leading to reduced descriptions of flow microstructure based on conditionally scaled data are formulated and are evaluated using the measured concentration profiles. The analysis provides a quantitative estimate of the respective contributions of large-scale and small-scale motion to the overall variability of the concentration field.

The measurements show the development of large-scale vortical structures in the mixing region adjacent to the central jet. These structures result in instantaneous radial profiles that differ considerably from the classical time-averaged Gaussian profiles measured previously using single-point measurements. The profiles typically consist of one or two plateau regions of relatively uniform concentration and are consistent with planar measurements obtained by other investigators in constant density and reacting flows. The results suggest a mixing model in which the dominant mechanism for entrainment is large-scale engulfment of surrounding air by the vortical structures, followed by rapid mixing with jet fluid. Conventional time-averaged statistics (mean, RMS fluctuations, and probability distributions) can be interpreted in terms of this large-scale structure. C1 ALTEX TECHNOL CORP,SANTA CLARA,CA 95054.

J. Ramirez et al., Digest of Technical Papers, 6th IEEE Pulsed Power Conference (Institute of Electrical and Electronic Engineers, New York, 1987), p. 294], pulsed, electron beam has two windows of stable transport in long drift cells filled with N-2 gas terminated by a bremsstrahlung producing target: a low-pressure window (between similar to 1 and similar to 100 mTorr) that is dominated by propagation in the semicollisionless ion-focused regime (IFR), and a high-pressure window (between similar to 1 and similar to 100 Torr) that is dominated by propagation in the resistive collisional regime. In the transition region between the two windows, beam plasma-electron instabilities significantly disrupt propagation. Propagation in both regimes (the IFR at early time and the collisional at later time) is observed from similar to 5 to similar to 100 mTorr, which produces two distinct bremsstrahlung pulses from the single injected beam pulse. As the pressure increases, two-stream instabilities terminate IFR propagation and the associated bremsstrahlung pulse earlier and earlier in time. Above 5 mTorr, the instability is sufficiently quenched by gas collisions that propagation in the collisional regime back in the beam body occurs, leading to a second propagation and associated bremsstrahlung pulse. Above 200 mTorr, the gas breaks down too rapidly for a significant IFR pulse to form, and for higher pressures only a single pulse in the collisional regime is propagated. Reasonable stability in the collisional regime is not achieved until pressures exceed 1 Torr. C1 MISSION RES CORP,ALBUQUERQUE,NM 87106. KTECH CORP INC,ALBUQUERQUE,NM 87110.

Tenner (World Scientific, Singapore, 1991), p. 475] has been used to study applied-B ion diodes. The impedance behavior of the diode in these simulations is in good agreement with both analytic theory and experiments at peak power. The simulations also demonstrate the existence Of electromagnetic instabilities which induce divergence in the ion beam. Early in time, there is an instability at high frequency relative td the ion transit time tau(i), and the resulting beam divergence is low. However, later in time, the system makes a transition to an instability with a frequency close to 1/tau(i), and the ion beam divergence rises to an unacceptably high value. The transition is associated with the build-up of electron space charge in the diode, and the resulting increase in the beam current density enhancement (J/J(CL)). Using different schemes to inhibit the electron evolution, the transition has both been postponed and permanently eliminated, resulting in Li+1 ion beams with a sustained divergence of similar to 10 mrad at an energy of similar to 10 MeV.

The severity of Eutypa dieback on individual grapevines was assessed in 1991 and 1992 as the proportion of the vines' spurs killed or symptomatic. In each year, Eutypa dieback caused a significant reduction in yield of infected vines compared with healthy vines. The linear relationship between disease severity (d) and yield (y), expressed as a percentage of the yield of healthy vines, was y = 101.0 - 90.26d (r(2) = 0.70) in 1991, and y = 100.1 - 98.81d (r(2) = 0.79) in 1992. The slope of this relationship was not significantly different between years or among five vineyards of two cultivars (Chenin blanc and French Colombard). Yield reduction was primarily due to a diminished number of clusters per vine, while the effects of disease on mean cluster weight were smaller and not always significant. The effect of disease severity on vegetative growth, measured as pruning weight, was significant in two of three vineyards in 1991 and both of two vineyards in 1992. Linear slopes of the pruning weight-disease severity relationships ranged from -29.5% (r(2) = 0.06) to -67.4% (r(2) = 0.46) per unit disease severity. Yield reductions for whole vineyards, estimated from the regression models, ranged from 30.1 to 61.9%, depending on mean disease severity. Records for Chenin blanc vineyards in Merced County, CA, revealed a trend of declining yields beginning at 12 yr of age, which closely followed the period of rapid increase of Eutypa dieback. In Barbera vineyards, which are rarely affected by Eutypa dieback, yields increased up to age 10 and then remained constant. C1 OKLAHOMA STATE UNIV,WES WATKINS AGR RES & EXTENS CTR,LANE,OK 74555.

The key to the role of HRGPs in cell wall self-assembly and cell extension lies in their chemistry, which is dependent on extensive posttranslational modifications (PTMs): hydroxylation, glycosylation, and cross-linking. Repetitive peptide motifs characterize HRGPs. One or more repetitive peptide motifs and their variants, singly or in combination, may constitute functional sites involved in various aspects of cell wall assembly, as follows: (i) X-Hyp(n) including Ser-Hyp(4) (arabinosylation site, molecular rigidity, and reptation). (ii) Pre-Hyp-Val-Tyr-Lys and variants (putative intermolecular cross-links, adhesion, cohesion, and possible B-turns). (iii) Tyr-X-Tyr-Lys (intramolecular isodityrosine [IDT] cross-links increase molecular rigidity and hydrophobicity). (iv) (Glyco)peptide palindromes (centrosymmetric domains: putative self-assembly nucleation sites). (v) Ionic interaction sites (protein-protein and protein-carbohydrate cross-links). (vi) Hyp and Ser glycosylation sites (enhance conformational stability and molecular recognition). (vii) Extensin modules in chimeric proteins (e.g. solanaceous lectins). Rules for the post-translational modifications are emerging: (i) Hydroxylation of proline residues may depend on multiple, sequence-specific prolyl hydroxylases rather than on a single (polyproline-II) conformation-dependent enzyme. Furthermore, Lys-Pro, Tyr-Pro, and Phe-Pro are not hydroxylated, while Pro-Vat is always. (ii) Contiguity of Hyp residues probably determines the extent of Hyp glycosylation, blocks of tetrahydroxyproline (Hyp(4)) being the most highly arabinosylated, while single non-contiguous Hyp residues are rarely arabinosylated, although they are likely attachment sites for the larger arabinogalactan substituents of gum arabic glycoprotein and arabinogalactan-proteins. (iii) While intramolecular cross-links involve IDT, unidentified intermolecular cross-links most likely involve the Val-Tyr-Lys motif (perhaps also Val-Lys-Pro-Tyr-H is-Pro), probably as an adduct between Tyr and Lys catalyzed in vitro by a pl 4.6 extensin cross-linking peroxidase. Thus, we can classify HRGPs functionally as either cross-linking or non-cross-linking, i.e. CL- or NCL-extensins. Their protistan origin obscures the phylogenetic affinities of a single extensin-HRGP family due to their sequence divergence. We propose a phylogenetic series ranging from the minimally glycosylated basic RPRPs to the highly glycosylated acidic AGPs. Furthermore, based on similarities between dicots and gymnosperm extensins, and their marked-difference from graminaceous monocot extensins, graminaceous monocot and dicot lines may have diverged as early as the progymnosperms. The origin of the embryophytes (land plants) is an even more open question, the nearest extant algal relatives being unknown. The Charophyta, frequently suggested as ancestral to the embryophytes, seem unlikely as the Charalean cell wall of Chara and Nitella lacks hydroxyproline.

To meet these criteria we devised a high-yield method for isolating from plant tissue, DNA whose single-strand molecular length is greater than about 170 kb. Leaf tissue is embedded in agarose plugs, digested with Proteinase K in the presence of detergent, and treated with phenylmethylsulfonyl fluoride (PMSF). The agarose plugs are then soaked with buffer appropriate to the desired enzyme treatment. Evaluation of the DNA on neutral and alkaline gels indicates its high molecular length and low frequency of single-strand breaks. The DNA can be digested with damage-specific and other endonucleases. The method is especially suitable for DNA damage quantitation, as tissue processing is carried out immediately after harvesting (allowing DNA lesion measurement at precisely known times after irradiation), and many samples can be easily handled at once. It should also be useful for molecular analysis of large numbers of plant samples available only in small quantities. We here use this method to quantitate DNA damage induced by 297 and 365 nm radiation, and calculate the relative damaging effects of these wavebands in today's solar spectrum.

In most applications, the sources of neutral particles are high-energy beams employed either for heating or for the specific purpose of active plasma diagnosis. The transitions following charge exchange are particularly useful for determining the densities of fully stripped low-Z ions and for measuring ion temperatures and plasma rotation, although they have also been exploited for other purposes. In this review, the atomic physics considerations for interpreting the data. including the influence of the plasma environment, are reviewed, and examples of recent applications to fusion studies are presented.

We now find that both the partially purified human epsilonA-binding protein and cell-free extracts containing the cloned human m3A-DNA glycosylase release all four cyclic etheno adducts-namely epsilonA, 3,N4-ethenocytosine (epsilonC), N2,3-ethenoguanine (N2,3-epsilonG), and 1,N2-ethenoguanine (1,N2-epsilonG). Base release was both time and protein concentration dependent. Both epsilonA and epsilonC were excised at similar rates, while 1,N2-epsilonG and N2,3-epsilonG were released much more slowly under identical conditions. The cleavage of glycosyl bonds of several heterocyclic adducts as well as those of simple methylated adducts by the same human glycosylase appears unusual in enzymology. This raises the question of how such a multiple, divergent activity evolved in humans and what may be its primary substrate. C1 LAWRENCE BERKELEY LAB,DONNER LAB,DIV LIFE SCI,BERKELEY,CA 94720.

We evaluated the course of potentially atherogenic oxidative changes in low density lipoproteins (LDL) by monitoring the oxidation of PnA following its incorporation into buoyant (rho = 1.026-1.032 g/ml) and dense (rho = 1.040-1.054 g/ml) LDL subfractions. Copper-induced oxidation of LDL-associated PnA exhibited an initial lag phase followed by an increased rate of loss until depletion. Increased PnA oxidation occurred immediately after the antioxidants ubiquinol-10 and alpha-tocopherol were consumed but before there were marked elevations in conjugated dienes. Despite differences in sensitivity to early oxidation events, PnA oxidation and conjugated diene lag times were correlated (r = 0.582; P = 0.03), and both indicated a greater susceptibility of dense than buoyant LDL in accordance with previous reports. The greater susceptibility of PnA in dense LDL was attributed to reduced levels of ubiquinol-10 and alpha-tocopherol, which were almost-equal-to 50% lower than in buoyant LDL (mol of antioxidant/mol of LDL) and together accounted for 80% of the variation in PnA oxidation lag times. These results suggest that PnA is a useful probe of LDL oxidative susceptibility and may be superior to conjugated dienes for monitoring the initial stages of LDL lipid peroxidation. Differences in oxidative susceptibility among LDL density subfractions are detected by the PnA assay and are due in large part to differences in their antioxidant content.

Described are the results of high temperature equilibrium solvation studies coupled with Fourier transform infrared spectroscopy (FTIR) for the identification of polymorphic conversion. These results are augmented by data in Part II from differential scanning calorimetry (DSC), differential thermal analysis/thermogravimetric analysis (DTA/TGA), and optical hot stage microscopy((6)). The thermodynamic stability order of epsilon > gamma > alpha-hydrate > beta is shown, with the epsilon polymorph the most thermodynamically stable phase of HNIW at room temperature. The existence of multiple alpha-hydrate phases is shown to complicate the determination of the equilibrium P-T phase diagram of HNIW.

The FNF waveform is applied to the endcap electrodes of the ITMS during the laser-desorption period, and its amplitude and frequency spectrum are adjusted to resonantly eject all ions except those with selected mass-to-charge ratios. In single-pulse laser desorption, the FNF rapidly ejects desorbed matrix ions without reducing the number of target ions that are trapped. When the FNF is used in conjunction with multipole laser-desorption events, accumulation of target m/z ions results in a 40-fold increase in sensitivity over single-shot laser desorption. In addition, the application of sequential filtered noise fields for multiple stages of mass spectral interrogation is demonstrated. C1 LOS ALAMOS NATL LAB,DIV CHEM SCI & TECHNOL,LOS ALAMOS,NM 87545.

This signal is usually interpreted as a measure of height change. Lateral forces from friction, surface geometry, or inclination of the cantilever to the surface also affect the slope due to cantilever buckling. We calculate the deflection of a hollow triangular model cantilever subject to both lateral and normal forces. The measured response of the servo circuit to an inclined, loaded cantilever is then determined. This shows (1) errors are always present in height measurements of structures on inhomogeneous surfaces; (2) the sensitivity to buckling can be reduced by repositioning the laser; (3) friction measurements can be accurately made by scanning in two directions and applying the proper calibration.

The particular phenomenon considered in detail is light-off, when the temperature of the converter changes dramatically from cold to hot somewhere within the converter. The initial position of light-off and the subsequent movement of this steep jump in temperature toward the inlet of the converter are analyzed. The method of matched asymptotic expansions is used to study light-off and to derive approximate formulas that determine its behavior in the limits of small heat diffusion and large activation energy. Numerical calculations are presented and are used to compare with the analytical formulas. These calculations reveal that the asymptotic results for small diffusion are quantitatively accurate, while those for small diffusion and large activation energy give the qualitative behavior of the solution but give poor quantitative predictions for the range of parameters encountered in practice.

However, little information is available concerning sources and regulation of N2O flux in this ecosystem. Experiments were made to determine the relative importance of nitrification, denitrification and abiotic sources to total N2O flux and to investigate the factors regulating N2O flux rates from an undisturbed shrub-steppe ecosystem. The contributions to N2O flux by nitrification and denitrification were estimated using acetylene (10 Pa) to selectively inhibit N2O production by nitrifiers. Abiotic sources of N2O were evaluated using sterilized soil. Factors limiting N2O production were evaluated by monitoring N2O flux rates from soil-cores amended with combinations of NO-N, NH4+-N, soluble C and water. The effect of wet-dry cycles on N2O flux was determined by wetting field dry soil to field capacity and monitoring N2O flux rates, soil NH4+-N, NO3--N and water content throughout a drying period. Our results showed that nitrification accounts for 61-98% of the N2O produced from soil at water contents below saturation and that denitrification is the primary N2O source at saturated water contents. No detectable N2O was produced by abiotic sources. In intact soil cores N2O flux rates were found to be most limited by water and N availability. Wetting of dry soil resulted in a pulse of N2O flux due to increased N availability. It is likely that this ecosystem exhibits relatively low N2O flux rates for much of the year due to low soil moisture and inorganic N contents. Since soil moisture content is generally well below field capacity in this ecosystem, nitrification must be the dominant N2O source. These results suggest that conditions favorable for substantial N2O production in shrub-steppe ecosystems probably exist only at times following precipitation events.

In support of these efforts, the AEETES thermal performance numerical model has been developed to predict thermal performance of pool-boiler and heat-pipe reflux receivers. The formulation of the AEETES numerical model, which is applicable to axisymmetric geometries with asymmetric incident fluxes, is presented in detail. Thermal efficiency predictions agree to within 4.1% with test data from on-sun tests of a pool-boiler reflux receiver Predicted absorber and sidewall temperatures agree with thermocouple data to within 3.3 and 7.3%, respectively. The importance of accounting for the asymmetric incident fluxes is demonstrated in comparisons with predictions using azimuthally averaged variables. The predicted receiver heat losses are characteriZed in terms of convective, solar radiative, and infrared radiative, and conductive heat transfer mechanisms.

This structure was recently observed in Si for pressures between the same two transitions. The energy of the Imma phase of Ge is found to be lower than or equal to the energy of the other two phases for all unit cell volumes. The structure of the Imma phase is shown to vary continuously with cell volume from a beta-Sn-like structure at large volumes to the sh structure at small volumes, when all three structures are described in terms of the Imma unit cell.

Preliminary experimental results yield exponents of 1/2 and 1/3, depending on the amount of hydrogen present in the sample. We extend Blumberg's theory for relaxation due to paramagnetic centers via dipole-dipole interaction in the absence of spin diffusion to obtain M approximately t(D/6) where D is the dimensionality of the system. This yields exponents of 1/2 and 1/3 for three- and two-dimensional systems, respectively. At long times the magnetization growth becomes exponential.

Plastic waste must be sorted to achieve the highest value recycled resin. Optical and artificial neural network technology may aid in reducing recycling casts by increasing the sorting speed and decreasing the fraction of impurity resins, A system for sorting waste plastics using near-infrared (near-IR) reflectance spectra and neural networks has been developed at Sandia National Laboratories, In this article, optimization of a backpropagation neural network used for sorting the near-IR spectra of postconsumer plastics is presented. The number of hidden layers, transfer function type, and preprocessing techniques were varied. For classification of resin spectra using neural networks, the most important factor appears to be data preprocessing. C1 SANDIA NATL LABS,DEPT SURFACE MOLEC SPECT & GAS ANAL,ALBUQUERQUE,NM 87185.

This need is reflected in the analytical surface science community by efforts to develop methods for detection of trace impurities on semiconductor substrates at extremely low levels. With improvements in standard techniques continually occurring, and with new methods of trace analysis always being developed, it is important to assess the relative abilities of the suite of surface analysis techniques available for materials characterization and to develop well-characterized standard samples for these comparisons. This paper reports on a collaborative effort to review the capabilities of several approaches to trace surface analysis. As a test case, Ni contamination of Si wafers in the dose range 10(14)-10(10) cm-2 has been chosen. The emphasis of this paper will be on the capabilities of SARISA (surface analysis by resonant ionization of sputtered atoms) as an example of laser post-ionization secondary neutral mass spectrometry for the detection of contaminants in the near-surface region. Results on analyses of the same standard samples by other techniques will also be presented. These techniques include total reflection x-ray fluorescence and heavy ion backscattering spectrometry. The results of this comparison show that there are several techniques that can accurately determine metal contaminations on Si wafers in this concentration range and that the method of choice depends on other considerations, such as speed or accuracy of analysis.

In a first experiment up to 10 monolayers of well-ordered iron oxide films were grown epitaxially onto Pt(111) substrates. A 1 monolayer thick film forms a hexagonal lattice with a lateral repeat distance of 3.2 angstrom, 15% larger than the lateral periodicity of Pt(111). Above 1 monolayer coverage the LEED pattern reveals a lateral repeat distance of 3.0 angstrom, indicating a contraction of the oxide lattice with respect to the first monolayer. This new LEED pattern shows half-order spots and is compatible with (2 x 2) reconstructed FeO(111) and bulk terminated Fe3O4(111) surfaces. By applying automated tensor LEED to many possible surface structures of these two iron oxides, 8 monolayer thick films were identified to be magnetite, Fe3O4. Auger electron spectroscopy (AES) measurements on these films also reveal a stoichiometry close to that of Fe3O4. In a second experiment the (111) surface of an alpha-Fe2O3 single crystal was prepared by Ar+ ion bombardment and subsequent annealing. Brief annealing to 900, 1000 and 1200 K in 10(-10) and 10(-6) mbar oxygen creates three different LEED patterns indicating structural transformations occurring in the surface region of this crystal. Prolonged annealing to temperatures between 900 and 1200 K stabilizes the same LEED pattern and gives identical intensity-voltage curves as obtained on the 8 monolayer thick films. Therefore the crystal surface region has been reduced to Fe3O4 and has the same surface structure as the epitaxially grown films. X-ray photoelectron spectroscopy (XPS) measurements on this surface also reveal a stoichiometry dose to that of Fe3O4. The best fit structure for both preparations corresponds to an unreconstructed, but strongly relaxed, polar (111) surface termination of magnetite that exposes 1/4 monolayer of Fe ions over a distorted hexagonal close-packed oxygen layer and minimizes the number of dangling bonds. The surface relaxations are probably driven by electrostatic forces. Our results indicate that minimization of both the number of dangling bonds and the electrostatic surface energy are important in determining the termination and relaxations of this polar metal oxide surface. The electrostatic surface energetics is qualitatively discussed within general, simple concepts applicable to all ionic crystals. C1 LAWRENCE BERKELEY LAB,DIV MAT SCI,BERKELEY,CA 94720.

Cr vapor-deposited at room temperature formed relatively flat films on MoS2(0001). The Cr underwent a limited chemical reaction with the MoS2 substrate to form a chromium sulfide and Mo metal. The Mo metal formed a thin layer between the Cr film and the MoS2 substrate. In contrast, reacted S was incorporated throughout the Cr film, with its concentration enhanced at the surface. Annealing the Cr-covered sample drove the reaction between Cr and MoS2, forming additional Mo metal that alloyed with Cr, and several adsorbed S species on the Cr film surface. Annealing also caused partial coalescence of the Cr-containing portion of the film, uncovering parts of the Cr-Mo alloy. The reactivity of Cr with respect to MoS2(0001) is greater than that of Fe and somewhat less than that of Mn. C1 AEROSP CORP,TECHNOL OPERAT,CTR MECH & MAT TECHNOL,EL SEGUNDO,CA 90245.

The system considered here are heptamers and dodecamers for the substrate temperature of 100 K. Using molecular dynamics simulations with the corrected effective medium potentials for Pd, Cu and Rh, we have found that an adatom either diffuses on the cluster or incorporates itself into the cluster depending on the size of clusters and the kind of metals in the gas/cluster system. We also discovered that incorporation of a deposited gas atom into a surface cluster at 100 K was not a consequence of the reduction of the barrier heights at the step edges and that the type of post-impact dynamics for hexagonal heptamers depends on the impact point.

To evaluate and compare the effectiveness of available sequential-design sensitivity tests in this setting, several such tests were compared through Monte Carlo simulation. Samples of size 20, 35, and 50 were used to estimate the .99 and .999 quantiles of the probit model. Each test was evaluated using initial parameter estimates equal to the parameters of the model and then using inaccurate estimates. The effect of assuming the probit model when the true model was legit, generalized logistic, or Type I extreme-value was also studied. Our results show that, when the model is correctly specified, tests designed to estimate the model parameters and subsequently to estimate quantiles as a function of the model parameters provided more accurate quantile estimates than tests designed to estimate a specified quantile. The tests that estimated model parameters, however, were more affected by model misspecification. C1 SANDIA NATL LABS,DEPT STAT & HUMAN FACTORS,ALBUQUERQUE,NM 87185.

'MN9'. Ten days after complete shoot defoliation or decapitation, the stem starch concentration of treated plants declined to one-half that of intact plants, and there were similar or greater reductions in the concentrations of glucose, fructose, sucrose, galactose, and shikimic acid. Partial shoot defoliation (50%) and complete disbudding had no effect on stem starch concentration, but stem sucrose concentration was reduced in all treatments. Sucrose depletion preceded and may have induced other changes in the carbon status of plants subjected to leaf or shoot removal. Four days after shoot decapitation, the sucrose concentration of roots of treated plants was reduced to 25% that of intact plants. However, the concentrations of fructose and glucose increased in the roots of treated plants and was followed by the accumulation of shikimic acid, salicyl alcohol, unknown compound A and salicin. The possible role of increased concentrations of root organic solutes in the water relations and regrowth process of decapitated plants is discussed.

For integrable models a universal algorithm for the construction of soliton-like solutions is discussed in detail. This might be generalized to many dimensional cases and its efficacy for several examples exceeds that of the stadart inverse scattering transform method. For nonintegrable models we focus mainly on methods of studying the stability of soliton-like solutions, since stability problems become the most substantial ones, when one turns to a description of many dimensional solitons. We pay a special attention to those stable localized structures, which are not endowed with topological invariants, since for topologically nontrivial structures there exist efficacious method stability analysis, based on energy estimates. Here the principal topics of the Lyapunov's direct method in application to distributed systems are discussed. Efficacious criteria of stability for stationary the method of functional estimates and discuss the stability of plasma solitons of the electron phase hole type. C1 JOINT INST NUCL RES,DUBNA,RUSSIA.

Clams accumulated substantial PCB residues at most sites monitored, with the exception of the sites closest to chlorinated discharges. Clams placed nearest to the chlorinated stream reaches consistently underestimated PCB contamination, based on the amount of PCBs found in fish and sediment at those sites. In a separate experiment, clams exposed in stream-side tanks to untreated (total residual chlorine ranged from 0.02-0.07 mg-1 L daily) and dechlorinated stream water exhibited differing degrees of valve movement, growth, and PCB accumulation after a four-week exposure to the two treatments. Clams exposed to untreated (chlorinated) stream water closed their shells more often, exhibited less growth, and accumulated substantially lower PCB concentrations than clams exposed to dechlorinated stream water. Clams apparently close their shells to avoid chlorine exposure, thus isolating clam tissues from PCBs found in the stream water and in die clams' food. Because chlorine and PCBs occur together in many industrial discharges, this finding is a significant consideration for monitoring programs that utilize clams to assess PCB bioavailability.

The methodology allows solute transport simulations, usually the main computational component of management models, to be run in parallel. The ANN technology, inspired by neurobiological theories of massive interconnection and parallelism, has been successfully applied to a variety of optimization problems. In this new approach, optimal management solutions are found by (1) first training an ANN to predict the outcome of the flow and transport code, and (2) then using the trained ANN to search through many pumping realizations to find an optimal one for successful remediation. The behavior of complex groundwater scenarios with spatially variable transport parameters and multiple contaminant plumes is simulated with a two-dimensional hybrid finite-difference/finite-element flow and transport code. The flow and transport code develops the set of examples upon which the network is trained. The input of the ANN characterizes the different realizations of pumping, with each input indicating the pumping level of a well. The output is capable of characterizing the objectives and constraints of the optimization, such as attainment of regulatory goals, value of cost functions and cleanup time, and mass of contaminant removal. The supervised learning algorithm of back propagation was used to train the network. The conjugate gradient method and weight elimination procedures are used to speed convergence and improve performance, respectively. Once trained, the ANN begins a search through various realizations of pumping patterns to determine whether or not they will be successful. The search is directed by a simple genetic algorithm. The resulting management solutions are consistent with those resulting from a more conventional optimization technique, which combines solute transport modeling and nonlinear programming with a quasi-Newton search. The results suggest that the ANN approach has the following advantages over the conventional technique for the test remediations: more independence of the flow and transport code from the optimization, greater influence of hydrogeologic insight, and less computational burden due to the potential for parallel processing of the flow and transport simulations and the ability to ''recycle'' these simulations. The ANN performance was observed upon variation of the problem formulation, network architecture, and learning algorithm.

It has been found in prior work to order in two steps, with the intermediate phase showing long-ranged ferromagnetic correlations within the intercalate plane, but no correlations between neighboring planes. We have probed the wave vector and temperature dependence of the static and dynamic spin correlations in detail, including measurements of the critical scattering, the quasielastic scattering from vortex diffusion and the spin wave excitations with and without an external magnetic field. Some of the predictions for a Kosterlitz-Thouless type transition are met in this compound, at least qualitatively, including an apparent jump in the spin stiffness at the critical point and the existence of a diffusive central peak in the scattering function possibly originating from vortex autocorrelations. However, there are some inconsistencies between our observations and recent analytical studies as well as Monte Carlo - molecular dynamics simulations of the vortex dynamics that prevent unambigous assignment of the upper critical temperature as a vortex-binding transition.

The data were taken with the E665 spectrometer, which was exposed to the 490 GeV muon beam of the Tevatron at Fermilab. The use of a streamer chamber as vertex detector provides nearly 4 pi acceptance for charged particles. The muD data are compared with the muXe data in terms of multiplicity distributions, average multiplicities, forward-backward multiplicity correlations, rapidity and transverse momentum distributions and of two-particle rapidity correlations of charged hadrons. The data cover a range of invariant hadronic masses W from 8 to 30 GeV. C1 ALBERT LUDWIGS UNIV,FREIBURG,GERMANY. ARGONNE NATL LAB,ARGONNE,IL 60439. FERMILAB NATL ACCELERATOR LAB,BATAVIA,IL 60510.

The suppression measured in central 200 GeV/A O-U and S-U collisions cannot be obtained from interactions of the J/psi with the primary nucleons alone. Absorption on primary and secondary hadrons can describe these data, however, provided the density of the secondaries is at least 0.8 fm-3 i.e., five times standard nuclear density.

MEASUREMENTS OF B(S)0 MESONS AT LEP USING D(S) AND PHI MESONS SO ZEITSCHRIFT FUR PHYSIK C-PARTICLES AND FIELDS LA English DT Article ID LUND MONTE-CARLO; JET FRAGMENTATION; B-MESONS; PHYSICS; Z0 AB The study of the properties of inclusive production of D(s) mesons and of events in which a phi and a muon are present in the same jet provides two independent measurements of the probability, f(s)w, for a heavy quark to hadronize into a strange B or D meson. The data sample analysed corresponds to 243,000 hadronic Z0 decays. The combined value of these measurements is f(s)w=0.19+/-0.06+/-0.08. From the flight distance distributions of D(s) and of (phi-lepton) secondary vertices, with the lepton emitted at high transverse momentum relative to the jet axis, two values are obtained for the B(s)0 meson lifetime. Combining these measurements with a previous result based on the study of D(s)-mu events, the B(s)0 meson lifetime is measured to be: 0.96+/-0.37 ps.

The films were (001) textured normal to substrate surface with a high degree of in-plane orientation with respect to the substrate's major axes. YBCO films showed superconducting transition temperature (T-co) at 91 K and critical current densities were found to be 2-3 X 10(6) A/cm(2) at 77 K and zero field. An ion beam minimum channeling yield of 16% was obtained for YBCO films, indicating high crystallinity. The orientation relationship for this epitaxial multilayer structure was found to be (100) YBC parallel to(100) SR parallel to(100)Pt parallel to(100) MgO. This result showed that high-quality superconducting thin films can be deposited on metal with an appropriate buffer layer.

The adsorption of zincate ions on the platinum electrode is demonstrated by modifications of the voltammograms and shifts in rest potentials. Interference with the hydrogen reactions in the voltammograms by zincate ions prevents the use of the H-2/Pt reference electrode for rest potential measurements in zincate-containing solutions.

We examine both materials in the wurtzite and zinc-blende structures and compare these results with previous calculations for BN. Effects due to the s, p and d angular components of the Al and Ga potentials are studied. Because the charge densities of both AlN and GaN are dominated by N, the difference in the valence band charge density between these compounds is small. This is the reason that they have similar ground-state structural properties. Individual electronic levels at high-symmetry points, however, are altered by several electronvolts because of changes in the cation potential. This is the origin of the significant difference between the fundamental gaps of these compounds. C1 UNIV CALIF BERKELEY, DEPT PHYS, BERKELEY, CA 94720 USA.

The surface and internal structure as a function of annealing time is compared for two sets of films 680 and 800 Angstrom in thickness. For the thicker films the equilibrium morphology shows no surface features since the film thickness is 2.5L where L is the period of the lamellar microdomain morphology. The thinner films, 2.1L in thickness, exhibit hole formation over 40% of the surface. In both cases the multilayer organization proceeds from the substrate upward by chain transport through channels which perforate the developing layers. For short annealing times a sharp increase in surface roughness is seen, which may be linked with the wetting of PMMA-rich surface regions by polystyrene. At longer times these height fluctuations decay or grow into holes, depending on the initial film thickness. C1 IBM CORP,ALMADEN RES CTR,DIV RES,SAN JOSE,CA 95120. MIT,CAMBRIDGE,MA 02139.

In particular, we show that CP violation in the Higgs-gauge sector is allowed only if the custodial SU(2) symmetry is broken. We exploit these facts to constrain CP violation using the experimental bounds on rho - 1. CP nonconservation in the Higgs-fermion interactions can also be constrained in a similar way although a possible exception is pointed out.

Our regularisation method for one loop is based on the method of Pauli and Villars. We use it to calculate the renormalisation factors for the corresponding effective actions, clearing up some discrepancies in the literature. In particular, it will be shown explicitly that vector gauge transformation invariance and Haar invariance of functional integral measures impose different requirements, but they are related by a counterterm (which is local in terms of group variables). For higher loops, we use the method of covariant derivatives combined with Pauli-Villars to argue that the one-loop result remains unaltered. C1 UNIV LEUVEN,INST THEORET FYS,B-3001 LOUVAIN,BELGIUM.

Data from relatively high statistics runs at relatively small bare fermion masses of 0.005, 0.01, 0.02 and 0.03 (lattice units) are presented. Three independent methods of data analysis indicate that the critical point occurs at beta = 0.225(5) and that the monopole condensation and chiral symmetry breaking transitions are coincident. The monopole condensation data satisfies finite-size scaling hypotheses with critical indices compatible with four-dimensional percolation. The best chiral equation of state fit produces critical exponents (delta = 2.31, beta(mag) = 0.763) which deviate significantly from mean field expectations. Data for the ratio of the sigma to pion masses produces an estimate of the critical index delta in good agreement with chiral condensate measurements. In the strong coupling phase the ratio of the meson masses are M(sigma)2/M(rho)2 almost-equal-to 0.35, M(A)1(2)/M(rho)2 almost-equal-to 1.4 and M(pi)2/M(rho)2 almost-equal-to 0.0, while on the weak coupling side of the transition M(pi)2/M(rho)2 almost-equal-to 1.0, M(A)1(2)/M(rho)2 almost-equal-to 1.0, indicating the restoration of chiral symmetry.

The symmetry properties of the system are studied. The relationship between intrinsic localized states and the soliton of the Ablowitz-Ladik NLS is discussed, including the role of discretization as a mechanism controlling collapse. It is pointed out that a staggered localized state can be viewed as a particle of a negative effective mass. It is shown that staggered localized states can exist in the discrete dark NLS. The motion of localized states and Peierls-Nabarro pinning are also studied. C1 LOS ALAMOS NATL LAB,CTR NONLINEAR STUDIES,LOS ALAMOS,NM 87545.

The absence of candidates established an upper limit on the monopole flux of 5.6 x 10(-15) cm-2 sr-1 s-1 at 90% confidence level in the velocity range of 10(-4) less than or similar to beta < 4 x 10(-3). This result places a new constraint on the abundance of monopoles trapped in our solar system. C1 INFN,I-70126 BARI,ITALY. UNIV BOLOGNA,DIPARTIMENTO FIS,I-40126 BOLOGNA,ITALY.

Cross sections and beam-polarization asymmetries for theta(p)lab = 60-degrees - 100-degrees and E(gamma) - 195-304 MeV are compared with a microscopic calculation which includes one-, two-, and three-nucleon absorption mechanisms. One- and two-nucleon absorption alone fails to describe the data at low proton momenta. The inclusion of three-nucleon absorption significantly improves the comparison with the measured cross sections. However, some features of the asymmetry distributions are not explained.

The onset of the NQR Zeeman splitting at T(N) is abrupt but continuous, indicative of a second-order phase transition with either a crossover in critical behavior just below T(N) or a very small critical exponent beta less than or similar to 0.1. The absence of any anomaly at T(N) in the La-139 electric field gradient indicates no accompanying structural distortion. C1 LEIDEN UNIV,KAMERLINGH ONNES LAB,2300 RA LEIDEN,NETHERLANDS.

The dependence of the current on the shape of the potential, and on the shape of the power spectrum of the noise is illustrated. It is demonstrated that the direction of the current is opposite when the power spectrum of the noise has a minimum or maximum at zero frequency. A simple physical mechanism for this behavior is suggested. The behavior of the system in the limit of slow noise (t(c) >> t(r)) is also discussed.

We study the Ward identities in some detail, with several central results. First, we solve for the correlators of the affine-Sugawara nests, which are associated with the nested subgroups g superset of h(1) superset of ... superset of h(n). We also find an equivalent algebraic formulation which allows us to obtain global solutions across the set of all affine-Virasoro constructions. A particular global solution is discussed which gives the correct nest correlators, exhibits braiding for all affine-Virasoro correlators, and shows good physical behavior, at least for four-point correlators at high level on simple g. In rational and irrational conformal field theory, the high-level fusion rules of the broken affine modules follow the Clebsch-Gordan coefficients of the representations.

We include a brief discussion of angle integrated measurements acquired with X-ray photoemission and with ultraviolet photoemission. However, the major effort is devoted to a discussion of high resolution angle resolved photoemission spectroscopy (ARPES) studies on samples cleaved in high vacuum at cryogenic temperatures. These samples show a clear (metallic) Fermi edge cutoff, and band dispersion that is generally consistent with predictions of band theory. Mostly, electron states lying close to E(F) (within about 1 eV) are examined. The highly two-dimensional nature of the YBCO structure allows for reasonably straightforward measurement of the Fermi surface; consequently the Fermi surface has been measured in some detail. Evidence, from ARPES measurements, for the existence of a van Hove singularity near the Fermi level, that might play a role in high T(c) superconductivity, is considered. Systematic studies are presented that show changes in the band structure and Fermi surface as the oxygen stoichiometry is reduced; with oxygen depletion, YBCO changes from a high T(c) superconductor to a magnetically ordered insulator. ARPES studies of YBCO crystals with Co and Zn atoms substituted on Cu sites are also included. When ARPES measurements are performed at room temperature, the samples show rapid degradation; consequently, room temperature measurements are not extensively reviewed here. Despite extensive studies, some issues still remain largely unresolved or controversial. The ARPES technique is surface sensitive and the cleavage plane has not been clearly identified; consequently concerns associated with measurement of the cleaved surface are addressed. Efforts, generally unsuccessful, to observe a superconducting gap, are discussed. RP VEAL, BW (reprint author), ARGONNE NATL LAB, DIV MAT SCI, ARGONNE, IL 60439 USA.

The performance of polyphosphazene polymers has been studied at the Idaho National Engineering Laboratory; the helium from methane separation performances of poly [bis(alkyl and aryl)phosphazene] membranes are presented in tl;is paper. Separation performance was measured in the 30 to 125 degrees C temperature range. Two feed gas mixtures (supplied by the U.S. Bureau of Mines) having initial helium concentrations of 2 and 34% were used. The resulting separation factors and fluxes are reported. Transport of these gases through the membrane was found to be a permeability-size-controlled process. RP PETERSON, ES (reprint author), IDAHO NATL ENGN LAB,POB 1625,IDAHO FALLS,ID 83415, USA.

The proton spectrum of clinoptilolite is Gaussian in shape, while that of heulandite is a (reduced splitting) Fake doublet. Studies of clinoptilolite from five different locations and heulandite from nine different sites agree with this observation. These results suggest a simple nondestructive NMR method for distinguishing heulandite from clinoptilolite. Dehydration experiments are particularly informative. Proton line widths of clinoptilolite as a function of the dehydration temperature reveal three types of water binding, none being absorbed water. Similar studies with heulandite reveal a change from the Fake doublet to a Gaussian, which is probably associated with the heulandite to heulandite B transformation; Al-27 and Si-29 NMR studies of clinoptilolite indicate a change in framework structure and/or cation binding with dehydration. Al-27 NMR of heulandite exhibits an increase in line width with dehydration temperature to 175 degrees C. At this temperature the increase stops and the line width remains constant to 215 degrees C, the maximum temperature studied. This agrees with the proton studies and is attributed to the heulandite to heulandite B transformation. Si-29 NMR of heulandite reveals a framework structural change and/or cation binding with dehydration. All of these observations are reversible upon rehydration.

Ab initio molecular orbital theory has been used to calculate equilibrium structures, normal-mode vibration spectra, and torsional potential energy surfaces of TEA using the STO-3G, 3-21G, and 6-31G* basis sets. Inelastic neutron scattering (INS) has been used to measure the vibrational spectra of TEA in the iodide salt, zeolite beta, and SAPO-34 molecular sieve in the range 0-400 cm(-1). In the theoretical calculations, four local minima corresponding to D-2d, S-4, C-1, and C-2 structures were located in the potential energy surface of the free TEA cation. Their relative energies at the HF/6-31G* level were 0.0, 0.8, 3.5, and 6.8 kcal/mol, respectively. A search of the potential energy surface for the lowest energy paths between these conformers via ethyl torsions reveal that all the barriers were less than or equal to 13 kcal/mol. The small barriers indicate that all conformers should be accessible under the conditions of hydrothermal synthesis during molecular sieve crystallization. The HF/6-31G* vibrational frequencies of the four conformers indicate that the modes corresponding to methyl torsions are located in the region 238-374 cm(-1) and the modes corresponding to ethyl torsions are located in the region 76-176 cm(-1) From our assignments of the INS spectra, it is concluded that TEA adopts the minimum energy D-2d conformation in the channels of zeolite beta and the C-2 conformation in the chabazite cage of SAPO-34. The conformation in the iodide salt is verified as being S-4. C-13 NMR spectra are consistent with these conformation assignments. C1 ARGONNE NATL LAB, ARGONNE, IL 60439 USA.

Layer thickness was found to control the reaction pathway of the ternary composites. The critical layer thicknesses below which one avoids interfacial nucleation of binary compounds obtained previously for binary systems were useful guides for predicting ternary system behavior. For elemental layers thicker than the binary critical layer thicknesses, the ternary composites were found to initially form MoSe2. The MoSe2 subsequently reacted with the rest of the composite to form the desired ternary compound on further heating. For elemental layers thinner than the critical layer thicknesses for the binary systems, the ternary composites reacted to form the desired ternary compound without forming MoSe2.

Here we present five crystal structures of GS complexed with each of two substrates, Glu and AMPPNP (an ATP analog), with a transition-state analogue, L-methionine-S-sulfoximine, and with each of two products, Gln and ADP. GS of the present study is from Salmonella typhimurium, has Mn2+ bound, and is fully unadenylylated. Protein-metal-substrate interactions and small but significant conformational changes induced by substrate binding are defined by Fourier maps. On the basis of these maps, we propose a tentative structure-based enzymatic mechanism of glutamine synthesis with these steps: (1) ATP binds first at the top of the funnel-shaped active site cavity, adjacent to the n2 Mn2+; Arg 359 moves toward the Glu binding site. (2) Glu binds adjacent to then, Mn2+ at the bottom of the active site near a flexible loop (residues 324-328). As proposed earlier by Meister and others, Glu attacks the gamma-phosphorus atom of ATP to produce gamma-glutamyl phosphate and ADP. (3) The presence of ADP (but not ATP) moves Arg 339 toward the P(i) site, perhaps stabilizing the gamma-glutamyl phosphate, and moves Asp 50' of the adjacent subunit toward a putative ammonium ion site, enhancing binding of this third substrate. Deprotonation of the ammonium ion, perhaps by Asp 50', permits the resulting active species, ammonia, to attack the gamma-glutamyl phosphate, forming a tetrahedral intermediate. (4) This tetrahedral intermediate stabilizes the Glu binding loop, residues 324-328, because of the interaction of the positive charge on the gamma-amino group of the intermediate with the negative charge on the side chain of Glu 327, closing the path of Glu entry through the bottom of the active site funnel. (4) Phosphate leaves through the top of the active site and a proton from the gamma-amino group of the tetrahedral intermediate is lost, perhaps to Glu 327, to yield Gln. The absence of electrostatic interaction between Glu 327 and the product Gln permits the segment (residues 324-328) to open, allowing Gln to leave through the bottom of the active site and Glu to enter for the next catalytic cycle. These five crystal structures of GS-substrate complexes also suggest possible mechanisms for other reactions catalyzed by GS.

If this splitting is neglected, pseudo-spin becomes a good quantum number and the resulting scheme (the pseudo-Nilsson model) has a very simple interpretation. The pseudo-spin symmetry embodied in the realistic deformed average field is explored by comparing the single-particle energies and wave functions of the deformed Woods-Saxon model with the corresponding results of the pseudo-Nilsson model. The scheme is used to calculate the magnetic moments of deformed odd-A nuclei of the rare-earth region. C1 UNIV WARSAW,INST THEORET PHYS,PL-00681 WARSAW,POLAND.

Whereas the two-time correlation function only describes the propagation of fluctuations initially present, the equal-time correlation function is related to the source of stochasticity. For stable systems it yields the Einstein relation, while for unstable systems it determines the growth of the instabilities. These features are illustrated for unstable nuclear matter in two dimensions. C1 GSI DARMSTADT,W-6100 DARMSTADT 11,GERMANY. LAWRENCE BERKELEY LAB,DIV NUCL SCI,BERKELEY,CA 94720. LNS,CATANIA,ITALY.

The scalar pentagon integral can be expressed as a linear combination of box integrals, up to O(epsilon) corrections, a result which is the dimensionally-regulated version of a D = 4 result of Melrose, and of van Neerven and Vermaseren. We obtain and solve differential equations for various dimensionally-regulated box integrals with massless internal lines, which appear in one-loop n-point calculations in QCD.

Perturbative QCD predicts that the average squared parton transverse energy will depend upon the strong coupling constant (alpha(S)).

We find that there are-in addition to the stationary pulses reported previously-stable localized solutions that are periodic, quasiperiodic, or even chaotic in time. An intuitive picture for the stability of thee time-dependent localized solutions is presented and the novelty of these phenomena in comparison to localized solutions arising for exactly integrable systems is emphasized.

It is shown that a drift wave launched with n/n0 much less than 1 in a dense region can propagate into a sparse region and amplify, in both a slab and a torus. Propagation is cut off by a large velocity increase, suggesting a simple explanation of the observed correlation between edge shear flows and improved confinement (H modes).

Near room temperature the charge dynamics are comparable to those of a heavy fermion compound in the incoherent regime; however, below 100 K the depletion of the low frequency conductivity signifies the development of a charge gap at low frequency (approximately 300 cm-1). The temperature dependence of the depleted spectral weight scales with the quenching of the Ce 4f moments, demonstrating that the gap formation is due to the local Kondo coupling of charge carriers to the Ce magnetic moments. The spectral weight which disappears as the gap forms must be displaced to energies much larger than the gap. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545.

A flux lock-in state, manifested as a minimum in the rho(THETA,T,H) data, evolves as the system is cooled deeper into the mixed state. This observation provides compelling evidence for nonzero line tension of vortices in this highly anisotropic superconductor. The temperature dependence of the flux flow resistivity at perfect alignment is consistent with Bose glass theory of vortex localization at columnar defects.

The processes are described which determine the response of silicon detectors to alpha particles, particularly the energy dependence of the line shape. In this work particle implanted and passivated silicon (PIPS) detectors are assumed to have a thin dead layer at the front contact and an infinite sensitive volume. The incoming monoenergetic alpha particles lose energy in the dead layer where they develop a Gaussian energy distribution due to electronic energy-loss straggling. In the sensitive volume the alpha particles transfer most of their energy to electronic excitation and ionization (E(s,e)) and the remaining fraction to the production of lattice vibrations and crystal damage. The statistical distribution of E(s,e) has been calculated by Monte Carlo simulation and shown to be asymmetric. The energy E(s,e) is subsequently used for the creation of electron-hole pairs, which are measured by an amplifier system with a Gaussian contribution to the energy resolution due to electronic noise. This model permits a quantitative calculation of the detector response function to alpha particles, and the result is in excellent agreement with measured spectra. On the basis of this model the energy dependence of the alpha particle line shape is also discussed. C1 CEC,JRC,IRMM,B-2440 GEEL,BELGIUM. HAHN MEITNER INST BERLIN GMBH,W-1000 BERLIN 39,GERMANY.

These studies focused on the weakly fed 1/2(+)[631] rotational band. States populated in this band are expected to decay by electromagnetic transitions to the band head 1/2(+) state at an excitation energy of 161.7 keV. This state de-excites to the ground state of Pu-241 With a half-life of 0.88 mu s. The alpha-particle decay feeding these rotational band members was investigated by performing gamma-gamma and alpha-gamma coincidence experiments using a 56.3 kBq Cm-245 radioactive source. The alpha population of the more strongly populated bands was also investigated, and resulted in two previously observed gamma rays being confidently placed within the Pu-241 lever scheme. Four gamma rays that were previously unassigned can now be excluded from the alpha decay of Cm-245 as a consequence of the present study. C1 ARGONNE NATL LAB,ARGONNE,IL 60439.

Cyclotron at the Lawrence Berkeley Laboratory. Following chemical separation, we measured the U-231 (T-1/2 = 4.2 d) activity with semiconductor detectors. The gamma-ray, X-ray and conversion-electron data from singles and coincidence measurements confirmed the known level scheme of Pa-231. Almost all of the vacancies in the atomic K shell are produced by electron capture in the decay of U-231. Thus, the relative K X-ray intensities can be used in a straightforward manner to normalize the decay scheme and deduce photon emission probabilities. The gamma-ray data agree with previous values determined with NaI detectors, but were measured much more precisely in this work. C1 ARGONNE NATL LAB,DIV PHYS,ARGONNE,IL 60439.

The recovered NaI gamma-ray spectrum is automatically resolved using a linear least squares program. Over 2000 NaI spectra have been received from these remote sites. These spectra provide information on isotopes of current interest and serve as a data base for the future studies of other radionuclides which may become of interest.

Of these cDNAs (Id-1H, Id-1H', and Id-2H), two (Id-IH and Id-1H') appeared to be derived by alternative RNA splicing. Id-1H and Id-2H seem to be human homologues of mouse Id-1 and Id-2, respectively, and have potential to encode 154 and 135 amino acid proteins. The Id-1H and Id-2H mRNAs were barely detectable in quiescent early passage HDF; serum coordinately induced both mRNAs, with two peaks of expression, in early and late in G1. Antisense oligomers complementary to Id-1H and Id-2H mRNA prevented early passage HDF from entering the S phase of the cell cycle. The treatment of serum-stimulated early passage cells with the antisense Id-1H oligomer completely abolished Id-1H. In senescent cells, serum barely induced the Id-1H and Id-2H mRNAs, although the levels of c-myc expression induced were similar in early passage and senescent cells. The expression levels of these Id genes vary among immortal human cell lines. Both genes were overexpressed in VA4 SV40-transformed lung fibroblasts and EJ-1 bladder carcinoma cells, while these genes were expressed at a very low level in SVts8 cells derived from SV40 tsA-transformed TIG-3 cells. SVts8 cells may acquire some function redundant to Id proteins. HT1080 fibrosarcoma cells expressed the Id-1H gene but not the Id-2H gene, suggesting these Id genes may subserve redundant functions.

Intuitively, this width depends on the mobile phase how velocity, but no systematic study of this effect has yet been performed. On the other hand, constant pattern behavior and the theory of shock layer are well known in chemical engineering. Using this approach, and assuming competitive Langmuir isotherm behavior, an analytical equation is derived which relates the shock layer thickness (SLT) in displacement chromatography and the column design and operating parameters. Using this equation, it is possible to investigate the dependence of the SLT between two consecutive bands in the isotachic train on the mobile phase velocity, the concentration and the retention factor of the displacer and the separation factor of the two components. In displacement chromatography, the optimum mobile phase linear velocity (u(opt)(s)) for minimum shock layer thickness, or maximum recovery yield depends not only on the coefficients of axial dispersion and mass transfer resistance of the two components, as does the optimum mobile phase velocity (u(opt)(L)) in linear chromatography, but also on the retention factor and the concentration of the displacer. The results of the study of this analytical equation are in excellent agreement with those of numerical calculations. C1 UNIV TENNESSEE,DEPT CHEM,KNOXVILLE,TN 37996.

A noise sequence is added to the calculated profile to simulate an actual chromatogram. The elution by characteristic point (ECP) method of isotherm calculation is then applied to this profile, and the derived isotherm is compared with the initial one. Significant differences between the ''true'' and the ''measured'' isotherms are observed at low or moderate column efficiencies. The direct method of determination of the isotherm from the band profile based on the numerical solution of the inverse mathematical problem gives more accurate results than ECP, especially at low column efficiency. It is recommended to use the ECP method only when the column efficiency exceeds markedly 2000 theoretical plates. C1 UNIV TENNESSEE,DEPT CHEM,KNOXVILLE,TN 37996.

In this study, we demonstrate the separation of tryptic digests of bovine, Candida krusei and equine cytochrome c using a new electrospray ionization (ESI) interface for CE-MS that does not require additional sheath make-up fluid or mechanical assistance to aid the ESI process. The utility of this new CE-ESI-MS interface is demonstrated using a 10 mu m I.D. CE capillary where the injected sample amounts are in the 30 femtomole (of protein) region. The CE electroosmotic flow rates when aminopropylamine treated capillaries are utilized are in the 10 nI/min region for a relatively conductive buffer system (0.01 M ammonium acetate-acetic acid buffer system, pH 4.4 and a 300 V/cm field strength).

Incubation of HDL with Cu2+ resulted in a rapid decrease of Trp fluorescence intensity with time with a concomitant increase in Trp maximum emission wavelength (lambda(max)). LDL incubated with Cu2+ also showed a rapid decrease in Trp fluorescence intensity with time, but with no associated increase in lambda(max). The status of apo HDL and apo LDL was investigated after 4 h oxidation (4h-oxHDL and 4h-oxLDL respectively). With 4h-oxHDL, the shift in lambda(max) was not associated with protein dissociation but rather with protein crosslinking and formation of larger HDL species. Progressive increase in lambda(max) was observed in 4h-oxHDL with increase in guanidine hydrochloride (GuHCl) concentration; this was not due to protein dissociation. Although oxidation of LDL did not produce an increase in lambda(max), a significant increase in wavelength was observed when LCh-oxLDL was exposed to increasing concentration of GuHCl. SDS-polyacrylamide gel electrophoresis and nondenaturing gradient gel electrophoresis of the 4h-oxLDL indicated formation of smaller molecular weight protein fragments that were still associated with LDL. Ultracentrifugation of oxidized LDL in the presence and absence of GuHCl showed no dissociated protein. In summary, these data indicate the following: (a) lipid peroxidation has a direct effect on Trp residues in both HDL and LDL, (b) oxidation of HDL is associated with conformational change in apo HDL, crosslinking and formation of larger particles, (c) oxidized HDL have a more stable apolipoprotein-lipid association than native HDL, (d) oxidation of LDL is associated with changes in apo B, that by fluorescence are apparent only in presence of GuHCl and results in fragmentation of apo B without dissociation of protein or change in particle size, and (e) stability of apolipoprotein-lipid association is comparable in oxidized and native LDL.

The hierarchy follows from null states of the Knizhnik-Zamolodchikov type and the assumption of factorization, whose consistency we verify at an abstract level. Solution of the equations requires concrete factorization ansatze, which may vary over affine-Virasoro space. As a first example, we solve the nonlinear equations for the coset constructions, using a matrix factorization. The resulting coset correlators satisfy first-order linear partial differential equations whose solutions are the coset blocks defined by Douglas. C1 UNIV BONN,INST PHYS,W-5300 BONN 1,GERMANY.

According to laboratory studies, the increase in aerosol surface area would lead to a loss of ozone. Radiation measurements from the solar backscatter ultraviolet spectroradiometer are used to probe the absorbing and scattering properties of the stratosphere after the eruption. The backscattered radiation is enhanced for wavelengths greater than 290 nm, with a peak at about 302 nm. The enhancements associated with aerosol backscattering and ozone change can be separated. A decrease in column ozone of 8 to 30 Dobson units was deduced within the aerosol layer at an altitude between 20 and 30 km following the month of the eruption.

The present paper demonstrates the use of spectral reflectance data from satellite remote sensing to model net CO2 flux (NCF) of a tallgrass canopy at the Konza prairie, Kansas. A bidirectional reflectance canopy model was used to estimate seasonal changes in canopy leaf area index (LAI) from surface reflectances remotely sensed by SPOT 1 and Landsat 5 satellites. The radiation model was also coupled with leaf conductance-photosynthesis models to scale up stomatal conductance and NCF from individual leaves to canopy level according to radiation distribution inside the canopy. The satellite-data-driven model was able to closely simulate the seasonal change in LAI as well as the short-term variation of canopy LAI caused by the dry period during late July and early August in the area. Modeled canopy stomatal conductance (g(c)) and NCF agree with measurements within 0.16 cm s(-1) and 0.28 mg m(-2) s(-1), respectively, during the growth season from late May to late August. In October both measured and modeled NCF turned to small negative values as canopy photosynthesis diminished and predicted LAI approached zero. In addition to data scatter, some of the differences between modeled and measured g(c) and NCF may be attributed to uncertainties in seasonal changes of plant physiological status that were not detected by satellite data; some of the differences were caused by inadequate description of the dependence of nighttime CO2 flux of soil respiration on nearsurface turbulent mixing.

The internuclear distance between aluminum and proton nuclei associated with Bronsted acid sites is measured directly using spin echo double resonance (SEDOR) techniques. This distance is determined to be 0.243 +/- 0.003 nm, consistent with the value of 0.246 nm determined by applying the method of moments to the H-1 spectrum of ZSM-5. The method of moments is applied to the H-1 spectrum of silicalite, and the internuclear distance between protons associated with an internal silanol pair is measured as 0.26 nm.

Two distinct incommensurate iodine monolayer phases are observed. In both of these phases the structures compress with increasing potential (electrocompression). In the lower potential phase a (pX root 3) centered-rectangular iodine monolayer is observed in which the coverage (theta) increases from 36.6% to 40.9% (relative to the gold layer density) with increasing potential. At more positive potentials a rotated-hexagonal phase is formed, and theta increases from 41.5% to 44.5%. At the highest coverages, in both phases, the iodine-iodine nearest-neighbor spacing equals the van der Waals diameter of 4.3 Angstrom. Analysis of the specular reflectivity gives an iodine-gold interlayer spacing of 2.35 Angstrom and iodine coverages which are in good agreement with the in-plane diffraction results.

Experience in analyzing the data from light and heavy ion collisions in terms of distributions rather than moments suggests that conventional fluctuations of multiplicity and transverse energy can be well described by gamma or Negative Binomial Distributions (NBD). Multiplicity distributions from central (ZCAL) collisions of O-16 + Cu at 14.6 A GeV/c have been analyzed by the E802 collaboration as a function of the interval deltaeta greater-than-or-equal-to 0.1 in the range 1.2 less-than-or-equal-to eta less-than-or-equal-to 2.2. Excellent fits to NBD were obtained in all deltaeta bins. The k parameter of the NBD fit exhibits a steep linear increase with the deltaeta interval, which due to the well known property of the NBD under convolution, indicates that the multiplicity distributions in adjacent bins of pseudorapidity deltaeta approximately 0.1 are largely statistically independent. This result explains and demystifies ''intermittency.'' RP TANNENBAUM, MJ (reprint author), BROOKHAVEN NATL LAB,UPTON,NY 11973, USA.

The fermion operators are explicitly constructed in terms of the vector potential and the electric field. We carefully specify the regularization procedure involved in the definition of these operators, and calculate the fermionic bilinears and the energy-momentum tenser. The algebra of bilinears exhibits the Schwinger terms which also appear in perturbation theory. The bosonic Hamiltonian density is a local polynomial function of A(i) and E(i), and we check explicitly the Lorentz invariance of the resulting bosonic theory. Our construction is conceptually very similar to Mandelstam's construction in 1+1 dimensions, and is dissimilar from the recent bosonization attempts in 2+1 dimensions which hinge crucially on the existence of a Chern-Simons term.

SMALL X SO PHYSICS LETTERS B LA English DT Article ID EVENT AB An analysis is presented of scaling violations of the proton structure function F-2(x, Q(2)) measured with the Hl detector at HERA in the range of Bjorken x values between x = 3 x 10(-4) and 10(-2) for four-momentum transfers Q(2) larger than 8.7 GeV2. The structure function F-2 (X, Q(2)) is observed to rise linearly with In Q(2). Under the assumption that the observed scaling violations at small x less than or equal to 0.01 are described correctly by perturbative QCD, an estimate is obtained of the gluon distribution function G(x, Q(o)(2)) at Q(o)(2) = 20 GeV2 C1 RHEIN WESTFAL TH AACHEN,INST PHYS 1,AACHEN,GERMANY.

Short-lived specular beam oscillations at T = 150 K are observed with narrow beam full-width-at-half-maximum (FWHM) of less than 3% of the Brillouin zone. By studying the flux dependence of the growth at 150 K, we determine that the specular beam intensity is a function of the total amount deposited theta=Ft, independent of the deposition rate F. This is consistent with the presence of a non-thermal, constant diffusion length R(0). By studying the growth of the root 3 at higher temperatures where thermal diffusion operates, as a function of flux, we can estimate the non-thermal component of the diffusion length R(0) greater than or equal to 50 Angstrom.

The analysis implies a 2.1% contraction of the first interlayer spacing of the cleaned surface. For Cu/Ru(0001), counter-intuitively, the first Ru interlayer spacing is found to contract by an additional 0.7%. Linearized augmented plane wave (LAPW) calculations suggest that this surprising result can be attributed to H contamination of the reference ''cleaned'' surface. For (1 x 1) clean, Cu- and H-covered Ru(0001) slabs, the LAPW predicts 4.0%, 3.5% and 1.5% contractions, respectively, of the outermost Ru-layer separation. The agreement of these predictions with the LEED results is reasonably close if the experimental ''cleaned'' surface is identified with the H-covered slab of the calculations.

These results are in excellent agreement with an analysis of low-energy electron diffraction I-V spectra that yields changes in the first three interlayer spacings of 1.9%, 0.8%, and -0.4%, respectively [P.T. Sprunger, K. Pohl, H.L. Davis and E.W. Plummer, submitted]. The calculations also show that the outward relaxation is accompanied by a 2.8% decrease in the p sigma population of the surface-layer; atoms (p(sigma) is defined with respect to the surface normal). This is somewhat smaller than the 7.8% decrease reported to accompany the outward relaxation of the clean Be(0001) surface [P.J. Feibelman, Phys. Rev. B 46 (1992) 2532].

In harmony with recent X-ray diffraction results, the hex --> (1 x 1) transition occurs at lower potentials, similar to 0 V versus SCE, than in weakly adsorbing acidic media such as perchloric acid, consistent with an influence of hydroxide adsorption. The dynamics of the reverse (1 x 1) --> hex transition accelerate markedly as the potential is lowered below about - 0.35 V versus SCE. Carbon monoxide adsorption, induced in 0.1M KOH at negative potentials, facilitates the formation of a notably homogeneous hex phase. C1 PURDUE UNIV,DEPT CHEM,W LAFAYETTE,IN 47907.

Infrared spectra revealed the presence of several uranium fluorides including the previously characterized UF4, UF5, and UF6. Lower laser energy favored new:absorptions at 400, 446, 496, and 561 cm(-1). These product absorptions increased stepwise during annealings which permitted diffusion and reaction of the fluorine. Similar studies with ClF produced the above absorptions plus a new band at 554 cm(-1) which is tentatively assigned to ClF2-. The first bands appearing at 400 and 446 cm(-1) are assigned to UF and UF2, respectively. The 496- and 561-cm(-1) bands are tentatively assigned to UF3 and F-3(-) respectively. Finally, uranium atoms were reacted with Cl-2. In addition to several absorptions due to UCl4, a new doublet at 312 and 308 cm(-1) is assigned to UCl2.

The ligation dynamics immediately following photodissociation have been investigated using picosecond TRIR spectroscopy and linear dichroism. The rate of photoinitiated transfer of CO from cytochrome a3 to Cu(B) was measured directly by monitoring the development of the transient Cu(B)CO absorption. In less than 1 ps, a stationary Cu(B)CO spectrum develops, which together with the CO infrared linear dichroism is constant until the CO dissociates from Cu(B) on a microsecond time scale. These observations indicate that the CO is transferred between metals and reaches its equilibrium conformation in less than 1 ps. This unprecedented ligand transfer rate has profound implications with regard to the structure and dynamics of the cytochrome a3-CU(B) site, the functional architecture of the protein, and coordination dynamics in general.

The films are c-axis oriented, epitaxially grown with a small mosaic spread of 0.2-degrees and a Rutherford backscattering spectroscopy channeling yield of approximately 9%. Cross-sectional transmission electron microscopy images reveal a sharp interface between NCCO and YSZ. The microwave surface resistance of NCCO films on YSZ buffered sapphire at 9.6 GHz is only 80 muOMEGA at 4.2 K in zero magnetic field, which is comparable to Y1Ba2Cu3O7-y films at similar reduced temperature, as a consequence of the decrease of structural imperfection in the film. The temperature dependence of the surface resistance and magnetic penetration depth in these films further confirms the s-wave BCS nature of NCCO.

In the melt, SANS results indicate that HDPE/LDPE mixtures form a single-phase solution for all concentrations, including blends containing high volume fractions (phi > 0.5) of branched polymer, for which multiphase melts have previously(1-3) been suggested. Proper accounting for isotope effects is essential to avoid artifacts, because the H/D interaction parameter is sufficiently large (chi(HD) similar to 4 X 10(-4)) to cause phase separation in the amorphous state for molecular weights (MW) > 150 000. In the solid state, after slow cooling from the melt (similar to 0.75 degrees C/min), the HDPE/LDPE system shows extensive segregation into separate domains similar to 100-300 Angstrom, in size. Both the shape and magnitude of the absolute scattering cross section are consistent with the conclusion that the components are extensively segregated into separate lamellae. Two-peak melting curves obtained for such mixtures support the SANS interpretation, and the segregation of components in the solid state is therefore a consequence of crystallization mechanisms rather than incompatibility in the liquid state.

When compared with computer simulations of hard-sphere-chain mixtures, the new equation of state gives better agreement than the original equation of state. The new equation of State indicates the simplifying physical assumptions which are required to obtain the well-known Flory-Huggins athermal entropy of mixing. The generalization presented here is applied to mixtures of hard-sphere-chain copolymers, where the spherical segments of a given chain may have different diameters. Illustrative calculations are presented for three types of copolymers (alternating, block, and random). C1 UNIV CALIF BERKELEY,DEPT CHEM ENGN,BERKELEY,CA 94720.

In W-171, four negative-parity and two(three) positive-parity bands have been established. A favoured (-, -1/2) configuration based on the (-, +1/2) configuration (E) coupled to the (+,1) configuration (AC) is suggested to be the nature of the continuation of the (-, -1/2) band above the AB crossing. This would be the first observation of the EAC configuration. The positive-parity decay sequences in W-171 provide an interesting extreme signature dependence for the interband M1 transition matrix elements, which is found to be well accounted for by theoretical expectations. In W-172 four negative-parity bands are established besides the positive-parity yrast sequence. C1 UNIV COPENHAGEN,NIELS BOHR INST,TANDEM ACCELERATOR LAB,DK-4000 ROSKILDE,DENMARK.

Design: Three-arm, placebo-controlled, randomized parallel trial. The study duration was 2.9 +/- 1.1 (SD) years. Setting: General community. Participants: 118 healthy, white women 3 to 6 years after spontaneous menopause, recruited by community announcement. Interventions: Random allocation to daily intake of 1700 mg of calcium (calcium carbonate given in divided doses with meals); placebo; or conjugated equine estrogens (0.625 mg; days 1 to 25), progesterone (10 mg; days 16 to 25), and 1700 mg of elemental calcium daily. Each participant received 400 IU of vitamin D daily. Main Outcome Measures: Total body calcium measured by delayed gamma neutron activation analysis and whole-body counting; bone mineral density of the spine, femur, and radius measured by photon absorptiometry. Results: Bone mineral density declined in the placebo group for the lumbar spine (-2.1%/y; 95% CI, -3.3 to -0.9), femoral neck (-2.0%/y; CI,-2.6 to -1.2), trochanter (-1.6%/y; CI, -2.4 to -0.8), Ward triangle (-2.7%/y; CI, -3.7 to -1.7), and total body calcium (-2.0%/y; CI, -2.2 to -1.8). Rates of change were intermediate for calcium augmentation compared with placebo and estrogen-progesterone-calcium but statistically significant compared with placebo for total body calcium (-0.5%/y; CI, -0.9 to -0.1; P = 0.006) and the femoral neck (-0.8%/y; CI, -1.4 to -0.2; P = 0.03). Conclusions: Although less effective than estrogen-progesterone-calcium, calcium augmentation alone significantly retards bone loss from the femoral neck and improves calcium balance in recently postmenopausal women. Dietary calcium augmentation should be recommended as a strategic option in helping to prevent early postmenopausal bone loss. C1 BROOKHAVEN NATL LAB,UPTON,NY 11973.

It is shown how models based on conformal solution (CS) theory or the Kirkwood-Buff (KB) solution theory or their combination may be used to investigate the cosolute effect on the solubilities of solids in supercritical (SC) fluid solvents. The generalized DK (GDK) formulae have been tested with the Peng-Robinson (PR) equation of state (EOS), by using it to compute approximate solute fugacity coefficients in dilute ternary SC solutions with two solids (solute and cosolute) at various dilutions and comparing with values based on the use of exact thermodynamic expressions with the PR EOS for fugacity coefficients in mixtures. The two sets of values are found to be in good agreement. Further tests along these lines consist of using both sets of solute fugacity coefficients in standard phase equilibrium equations to evaluate solute and cosolute mole fractions. Again, the two sets of values determined in this way show good agreement, thereby giving us grounds to suppose the GDK formulae are of sufficient accuracy to be used in the study of such mixtures. The CS model has been used in conjunction with the GDK formulae to successfully correlate several solid solubilities in SC CO, in the presence of a cosolute. Other potential applications of the GDK formulae include modeling the solubility of gases in liquids and the solubility of solids in SC fluid solvents containing an added entrainer.

Although this correlation can be taken as evidence that CO2 amplifies orbital forcing of temperature and is thus a strong greenhouse gas, this paper argues that estimating the strength of the CO2 warming effect from statistical evaluations of past climates based on CO2 and orbital forcing is hampered by strong multiple correlations between CH4, CO2, ocean currents, ice volume (and therefore albedo), dust, and nonseasalt sulfate. To estimate the strength of the greenhouse warming effect of CO2 from historical data, these correlations and multiple forcings should be taken into account.

An impenetrability constraint restricts the rod's lateral motion relative to the continuum, while an accompanying constraint allows axial slip subject to a release criterion. Satisfaction of these constraints is enforced via application of penalty and augmented Lagrangian regularizations. The proposed implementation is suitable for both static and dynamic implicit equation solving schemes, making it useful for a wide range of problems.

Together, these three components form a superconducting interconnect technology. The challenges encountered in developing such a technology for high-T-c superconductors involve factors associated with the materials, the circuits and the fabrication techniques. The use of pulsed laser deposition in conjunction with shadow mask patterning, photolithographic pattern definition, acid etching, ion-beam etching, and surface cleaning to produce multilayer interconnects from YBa2Cu3O7-x (YBCO) is discussed. These processes have been used to construct a variety of passive high-temperature superconducting components and circuits, including crossovers, window contacts, multiturn coils, and flux transformers. Integrated magnetometers incorporating superconducting quantum interference devices, multichip modules with semiconductor die bonded to YBCO interconnect structures, and analog-to-digital converters have also been successfully demonstrated.

This behavior is consistent with the crystallization of an amorphous phase present in unannealed samples in addition to the two previously observed crystalline phases: The rutile lattice is significantly strained in unannealed samples, with a(0) increased and c(0) decreased compared to the values for coarse-grained material. Normal bulk lattice parameters are obtained after annealing samples at 1073 K. Assuming that strain contributions to the measured low-angle peak breadths are negligible, measurements of the time and temperature dependencies of grain growth in nanophase rutile during annealing indicate a grain growth exponent of 0.64 +/- 0.06 and a grain growth activation enthalpy of 83 +/- 40 kJ/mol.

The decay kinetics were assumed to be governed by the rate of precipitate reconfiguration to grain boundaries. This assumption was confirmed by transmission electron microscopy (TEM) observations of the microstructure during resistance decay, and by studies of lines of two different widths. The results can be explained qualitatively from the microstructure of the lines. In particular, increasing the mean grain size slows the rate of resistivity decay, and establishing a bimodal distribution with a significant population of relatively large grains has the same effect. A simple model was developed to treat these effects quantitatively. The model assumes a cylindrical grain geometry and a uniform initial distribution of Cu and ignores the effect of intragranular precipitation. The model yields reasonable values for the activation energy for Cu diffusion in thin films, and predicts the correct dependence of the decay rate on grain size and grain distribution; however, it appears to overestimate the value of the preexponential factor D-0.

Independent control of the partial pressures of oxygen P(O-2) and thallous oxide P(Tl2O) was achieved through the use of a two-zone furnace. Stable ranges of P(Tl2O), P(O-2), and sample composition for individual Tl superconductors, including 2122, 2223, 1122, and 1223 (the latter intergrown with about 10% 2223) have been determined. A qualitative understanding of these stable ranges, based on the relative Tl content and formal oxidation state of the cations within a structure type, has been developed. From this information, equilibrium phase diagrams for Tl superconductors with Ca:Ba:Cu ratios of 1:2:2, 2:2:3, and 3:2:4 are proposed. These diagrams provide process information for the two-zone synthesis of bulk materials and thin and thick films. The superconducting transition temperatures of the individual phases produced by near-equilibrium processing are both reproducible and relatively insensitive to changes in the process conditions.

The ground-state depletion grating created by excitation with crossed beams is probed via either the S-2(($) over tilde B(1)A(1))-S-0(($) over tilde X(1)A(1)) or S-4(($) over tilde D(1)A(1))-S-0(($) over tilde X(1)A(1)) transitions. First-order LIGS spectra of the S-1-S-0 origin band at several grating-laser intensities reveal saturation-induced line broadening and significant saturation dips at line center. We develop a simple model, based on the anharmonic grating created in the saturated regime, and use it to fit the first-order data. From these fits we determine a saturation parameter and the linewidth of the S-1-S-0 origin absorption band, which is homogeneously broadened hue to rapid internal conversion (tau similar to 1 ps) in the S-1 state. We also observe LIGS spectra of the azulene origin taken at the second Bragg order of the induced grating; the observed second-order lineshapes are also fit with the anharmonic-grating model.

Here we report the observation of dispersed fluorescence spectra from single vibrational levels of the (II1)-I-1 state, consisting mainly of oscillatory bound-free continua which extend over some 7500 cm(-1). These spectra are analyzed using the semiclassical method of Child and LeRoy to determine the repulsive portion of the Mg.Xe(X(1) Sigma(+)) interaction potential up to nearly 1 eV in energy. Attempts were made to fit the experimental potential curves to several simple analytical functions, with a two-term Buckingham-type function yielding the best representation. A comparison of the repulsive portion of the Mg.Xe(X(1) Sigma) potential curve with that of the analogous Na.Xe(X(2) Sigma) curve determined similarly by Zimmerman and co-workers shows that the Na.Xe curve is even less repulsive than the Mg.Xe curve, even though the Mg.Xe potential is itself quite ''soft''. This can be rationalized by the ability of the more diffuse Na(3s) electron to ''back-polarize'' (spo hybridize) away from the Xe atom compared to the two Mg(3s(2)) electrons, thus reducing repulsion.

The ABC-DVR Green's function is efficiently computed by a Newton polynomial I expansion. We compute accurate reaction probabilities for the total energies and angular momenta required to obtain the thermal rate constants k(v=1,j)(T).

Evaluating the efficiency of Monte Carlo sampling, however, is at a rudimentary level and in need of new algorithms. Instead of the autocorrelation time as an efficiency measure for Monte Carlo simulations, we propose a direct method to characterize the movement of electrons in atoms or molecules during variational Monte Carlo computations. Further, the approach makes possible an efficient diagnostic tool to understand objectively many interesting issues in QMC. The usefulness of the method is demonstrated by comparisons among improved Metropolis algorithms and the original Metropolis algorithm. We also present an optimization method for choosing step sizes for Monte Carlo walkers. These step sizes are governed by the acceptance ratio of the electrons closest to the heaviest nucleus. Step sizes obtained for Ne and Ar are consistent with those obtained by the autocorrelation approach. Our study shows no evidence to support distinctions of core and valence electrons during simulations, and confirms that, in most cases, moving electrons individually is more efficient than moving ah the electrons at once. We find that ''trapped'' or ''stale'' configurations are due to a large quantum force, and a solution to this problem is suggested C1 UNIV CALIF BERKELEY,DEPT CHEM,BERKELEY,CA 94720.

The interaction energies were computed using a Hartree-Fock singles and doubles CI treatment; convergence of the calculation with respect to both basis set and configuration set was investigated. The surfaces have been represented quantitatively by standard Legendre polynomial expansions and qualitatively by novel pairwise additive potentials. With the pairwise additive models, successful fits require that the centers of force be orbital based as opposed to the typical nucleus-based form. Comparison of the surfaces would suggest that the final fitted surfaces are accurate to a few tenths of a kcal/mol up to 5-10 kcal/mol. In the following paper, the dynamical consequences of the small differences between ah the surfaces will be assessed by quantum dynamics calculations of cross sections and their subsequent comparison to experiment.

These calculations use the necessary two CH(X(2) Pi)+He potential energy surfaces as determined by a variety of ab initio techniques described in the preceeding paper. The calculated N=1-->N=2-7 cross sections confirm a previous prediction of preferential population of final state levels in which the electronic wave function of the CH molecule is antisymmetric with respect to reflection in the plane of rotation of the molecule. A generally good overall agreement is found between the energy-dependent cross sections determined in earlier experiments of Macdonald and Liu and appropriate averages of the calculated cross sections. However, small, systematic, qualitative discrepancies persist between theory and experiment Diagnostic calculations were carried out to identify the cause of these discrepancies. These calculations explored the influence of restrictions in basis set, configuration interaction, and functional forms used in fitting the potential energy surfaces. They also explored the consequences of the dynamical approximations of CH as a rigid rotor and the independence of the CH spin-orbit constant on the approach of the He partner. All these diagnostic calculations generally confirm the anticipated marginal influence of these approximations. C1 ARGONNE NATL LAB,DIV CHEM,ARGONNE,IL 60439.

First, annealed films of the asymmetric diblocks do not form the lamellar microstructure found in symmetric diblocks; their structure can instead be modeled in terms of the hexagonal packing of PEE cylinders observed in bulk small-angle neutron scattering measurements. However, the cylinders show in-plane distortions, which we interpret in the context of nonintegral layering. These distortions are amplified at the surfaces where the PEE assumes lamellarlike form. Second, as-cast films of the asymmetric diblock are characterized by a microstructure lacking long-range order, pinned between strongly segregated PEE at both surfaces. These films can be equilibrated through annealing, leading to the well-ordered structures described earlier. The changes with annealing are surprising given that both PEP and PEE are well above their glass transitions at room temperature. Finally, the block asymmetry and the associated cylindrical structure in the interior are also manifested in the surface topology. Thin films of asymmetric PEP-PEE are smooth on a macroscopic scale unlike their symmetric counterparts, which form islands on the surface to accommodate films of nonintegral lamellar thicknesses.

We show this peak is due to four autoionizing states of H-3. We also find that three of these resonance states cross along the symmetric stretch seam of the potential energy hypersurface. Such triple intersections may be expected in any polyatomic system which is of high enough symmetry to allow degenerate molecular orbitals. Their existence can profoundly affect the nuclear dynamics on these surfaces in a manner similar to that found in the more common cases of conical intersections between two surfaces.

This review article presents the work carried out on representative AB(5) and AB(2) type modified alloys (by partial substitution of with small additives of other elements). The purpose of the modification was to optimize the thermodynamics and kinetics of the hydriding/dehydriding reactions and to enhance the stabilities of the alloys for the desired battery applications. The results of our collaboration, to date, demonstrate that: (i) alloys prepared by arc-melting/annealing and mechanical alloying/annealing techniques exhibit similar morphology, composition and hydriding/dehydriding characteristics; (ii) alloys with the appropriate small amounts of substituent or additive elements - retain the single phase structure, improve the hydriding/dehydriding reactions for the battery applications, and enhance the stability in the battery environment - and (iii) the AB(2) type alloys exhibit higher energy densities than the AB(5) type alloy but the state-of-the-art, commercialized batteries are predominantly manufactured using AB(5) type alloys.

Using the a model, the steady-structure solutions fall into two groups, one for hot optically thin solutions and the other for cool optically thick solutions. We note that there are oscillatory modes with relatively short wavelengths only in the cool solutions, with typical frequencies below tens of Hz. The oscillation only exists within a certain range of accretion rate, and its frequency changes with the accretion rate. This result may be used to explain certain quasi-periodic oscillations (QPOs) observed in X-ray sources, where the frequency is several Hz in most cases for keV photons, as well as the very low QPO frequencies of about 100 keV recently found for GRO J 0422 + 32 and Cygnus X-1. In future observations, we expect to see a strong correlation between QPO frequency and the observed photon spectrum. C1 LAWRENCE LIVERMORE NATL LAB,DEPT PHYS,LIVERMORE,CA 94550.

The general form of the inflationary potential which produces such a spectrum is a hyperbolic function and is interpreted physically as a bulk viscous stress contribution to the energy momentum of a perfect baryotropic fluid.

High quantum efficiencies of 31% in liquid Xe, 17% in liquid Kr, and 10% in liquid Ar have been achieved. Excellent intrinsic energy resolutions of 2.8% FWHM for liquid Xe, 5.2% FWHM for liquid Kr, and 8.4% FWHM for liquid Ar have been measured for 5.5 MeV alpha particles. The enhancement of the quantum efficiency due to the applied electric field and the favorable effect of the negative electron affinity of liquid rare gases on electron extraction from the photocathode are discussed.

Both features are of great importance in hadron calorimetry, where it is the ''universal spectrum'' which makes possible the definition of an intrinsic e/h, and the increasing fraction of the energy going into pi(0)'s which leads to the energy dependence of e/pi. We present evidence for the ''universal spectrum,'' and use an induction argument and simulation results to demonstrate that the low-energy activity scales as E(m), with 0.80 less than or similar to m less than or similar to 0.85. The hadronic activity produced by incident pions is 15-20% less than that initiated by protons. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,BERKELEY,CA 94720. ARGONNE NATL LAB,ARGONNE,IL 60439.

The equation is solved by use of an alternating-direction-implicit iterative method together with a semioptimum sequence of acceleration parameters similar to those introduced decades ago for the solution of elliptic equations with positive-definite operators. The resulting technique is efficient and simple to program, permits the simulation of complex structures with modest storage requirements, and is of very general applicability.

Magnetic measurements show significant enhancement and stabilization of the high-T-c phase (2:2:2:3) fraction in iodinated Bi- and Tl-cuprates. Simultaneous use of Raman spectroscopy, analytical transmission electron microscopy (ATEM) with electron energy loss (EEL), and X-ray photoelectron (XPS) spectroscopy in conjunction with energy-dispersive X-ray analysis (EDX) and X-ray diffraction (XRD) show the presence of iodine in the lattice structure. On the one hand, Raman and XPS techniques provide evidence for the formation of I-3(-) and possibly I-5(-), in these systems. On the other hand, EEL experiments carried out on iodinated Bi-cuprates and KI and K+I3- crystallite standards provide evidence for I- ions in the structure. To explain the two sets of experiments we propose that polyiodides can be present in the host material with I-3(-) and I-5(-) preferentially located at grain boundaries or crystal defects.

Standard samples, prepared using sintering temperatures up to 950 degrees C in flowing oxygen, were superconducting with a midpoint near 30 K. About 0.75 formular unit of oxygen was removed by heating in flowing argon near 830 degrees C, producing a non-superconducting reduced material. Reoxidized samples were prepared by heating the latter in flowing oxygen near 400 degrees C. These regained the lost oxygen, but are not superconducting above 5 K. High-resolution synchrotron X-ray diffraction demonstrated the tetragonal structures of the standard and reduced specimens, as well as the orthorhombic structure of the reoxidized material. Portions of each sample were used for neutron powder diffraction studies, and the data were analyzed with the Rietveld technique. Structural parameters, including the Co occupancies on the two copper sites, were refined. The results are evaluated with respect to other neutron-diffraction, X-ray absorption fine structure, and Mossbauer data. The implications of these results in terms of a physical basis for the shift from tetragonal to orthorhombic symmetry are explored. We feel that oxygen reordering in the chain layers is the underlying reason for the lowering of the crystal symmetry. C1 S DAKOTA SCH MINES & TECH,RAPID CITY,SD 57701.

As the strontium concentration increases from x=0.0 to 0.5, the copper-in-plane oxygen distance decreases from 1.94 Angstrom to 1.90 Angstrom, the copper-copper distance from 3.88 Angstrom to 3.81 Angstrom, and the copper-axial oxygen (0(2)) distance from 2.71 Angstrom to 2.65 Angstrom, while the thallium-axial oxygen (0(2)) distance remains at 2.00 Angstrom, indicating an overall unit-cell contraction. We also find that the strontium atom is 0.14 Angstrom closer to the CuO2 plane than the barium atom. The contraction of the copper-in-plane oxygen bonds reflects an increase in the hole concentration in the CuO2 plane, leading to the observed decrease of T-c due to hole overdoping.

It uses successive approximations, first obtaining a number of coarse approximations, and then optimally linearly combining the coarsely defined functions to achieve an accurate end result. The more conventional approach of strict interpolation using radial basis functions does not necessarily yield high predictive accuracy, is very time-consuming for large data sets, and can also give suboptimal accuracy due to numerical problems with nearly singular systems of equations. The present approach considerably reduces computation time, and can improve the predictive ability of radial basis networks while retaining good training accuracy. Numerical examples for chaotic time series and some classical real world time series are presented. It is shown that the successive approximation radial basis network presented here is a useful tool for nonlinear modeling and prediction.

The equilibrium lattice constants and the formation energies of ordered alloys obtained with the LMTO-ASA method show that the calculations done with charge-neutral atomic spheres are closer to the experimental results than the conventional equivolume atomic-sphere-type calculations. In the case of disordered alloys, we find that charge-neutral atomic spheres are essential for the stability of these alloys within the KKR-ASA CPA method where the Madelung-type contribution is neglected. Our results clearly indicate that for disordered alloys any future implementation of a full-potential method within the single-site CPA should be carried out with charge-neutral cells rather than the Wigner-Seitz cells.

Two types of structural materials are studied: zinc-blende superlattices in the (111) direction and hexagonal wurtzite superlattices and ordered alloys in the (001) direction. Comparisons between band structures of these materials using folding of Brillouin zone points and the transition from an indirect to direct gap semiconductor in the zinc-blende compounds are discussed. All of the wurtzite structures studied are found to have direct band gaps with values between 3.5 and 5.8 eV. The 1 x 1 and 1 x 2 AlN/GaN zinc-blende superlattices have direct gaps of 4.4 and 4.3 eV, respectively, whereas the 2 x 1 AlN/GaN superlattice gap is 4.6 eV and is indirect. Several fundamental gaps are predicted and remain to be tested by experiment. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV MAT SCI,BERKELEY,CA 94720.

In contrast to an earlier report of a c(4 x 4) reconstruction, our current measurements reveal a related structure with 1 x 2 symmetry. The 1 x 2 structure is a disordered form of the c(4 x 4) reconstruction in which long-range correlations between dimer rows are preserved but dimer vacancies are located at random. Aside from reconstructions, ordered step structures were studied on samples with both high (2.2 degrees) and low (0.07 degrees) levels of miscut. Using Gaussian step-spacing distributions with widths of order the mean terrace size, a numerical model is used to reproduce measured truncation rod profiles in scans perpendicular to steps. We also use the model to follow the narrowing of the step-spacing distribution which occurs during growth. After the growth of several hundred angstroms of GaAs, truncation-rod profiles sharpen, accompanied by a shift in peak positions. The shift is due to an asymmetric weighting of the scattering from terraces of different widths: wide terraces make a greater contribution to the structure factor. For samples with a broadened distribution of step spacings, this effect results in a smaller peak splitting than that which would occur for an ideally miscut sample.

The tunneling rate presents an asymmetric peak, centered at the reduced energy Delta*, that decreases with increasing G. The integrated tunneling rate has a finite value for the phase shift at the Fermi level delta(0)=pi/2. Our results point to no localization of the heavy particle in this model.

Prompted by suggestions that FeSi may be strongly correlated in a similar class to the Kondo insulators, we present results for the electronic structure and optical properties for FeSi calculated with a self-consistent augmented spherical wave method. The calculated indirect gap (approximate to 0.1 eV) is roughly consistent with resistivity measurements which indicate a gap of about 50 meV. We calculate the optical response incorporating simple finite-temperature effects, namely, electron-phonon scattering of intrinsic carriers. We find that this provides a poor direct fit to recent infrared measurements. The number of intrinsic carriers is low compared to experimental observations, even with an ad hoc renormalization of the gap, and a strong scattering mechanism with attendant disordering of the band structure is required as well.

This class of compounds is unique in that the electrons are essentially confined to the individual clusters, while the latter are both large in size and close packed. We derive a general expression for the dispersion law of conduction-band plasmons, and apply it to alkali-metal-doped fullerides and quantum-dot arrays. We find that the dispersion relation is modified from the case of a homogeneous electron gas: it becomes measurably steeper and acquires a downward slope. This change is due to the appearance of a term which is determined by the density distribution of electrons within a unit cluster. Related electron-energy-loss spectroscopic data on the doped fullerides are discussed. C1 UNIV CALIF BERKELEY,DEPT PHYS,BERKELEY,CA 94720. UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,BERKELEY,CA 94720.

It has been argued that the probability distribution for the signature, induced by massless free fields, is peaked at the Lorentzian value uniquely in D=4 dimensions. This argument is reviewed, and certain consistency constraints on the generalized signature (i.e., the tangent-space metric eta(ab)(x)=diag[e(i theta(x)),1,l,l]) are derived. It is shown that only one dynamical ''Wick angle'' theta(x) can be introduced in the generalized signature, and the magnitude of fluctuations away from the Lorentzian signature delta theta=pi-theta is estimated to be of order (lp/R)(3), where lp is the Planck length, and R is the length scale of the Universe. For massless fields, the case of D=2 dimensions and the case of supersymmetry are degenerate, in the sense that no signature is preferred. Mass effects lift this degeneracy, and we show that a dynamical origin of the Lorentzian signature is also possible for (broken) supersymmetry theories in D=6 dimensions, in addition to the more general nonsupersymmetric case in D=4 dimensions.

In principle the global O(6,6) symmetry of the effective action can be employed to generate new solutions from the one presented here.

Accordingly, band profiles in overloaded chromatographic columns are best understood by considering the ideal model, while the process itself is most suitably modeled using the equilibrium-dispersive model. The former model assumes an infinite column efficiency, while the latter lumps the contributions of axial dispersion and mass transfer resistances into a single apparent dispersion coefficient. The properties and solutions of these models are reviewed. The conditions under which they give satisfactory results are summarized. The excellent agreement between the experimental band profiles of the components of binary mixtures and the individual band profiles calculated with the equilibrium-dispersive model is demonstrated. The degree of agreement is limited only by the accuracy with which the competitive equilibrium isotherms are accounted for. C1 UNIV TENNESSEE, DEPT CHEM, KNOXVILLE, TN 37996 USA.

As a result, it has become possible for most chromatographers to calculate rapidly the individual elution band profiles of the components of mixtures by integrating the differential mass balance equation of chromatography. It has become possible to find out rapidly what would be the effect of possible modifications of the experimental parameters. For conventional columns having a few thousand plates, the computation takes between a few seconds and a few minutes, provided a performing algorithm is used.

The threshold spectrum is compared to photoelectron and absorption data exhibiting features of both. The satellite intensity at zero kinetic energy is 3.8% of the 1s main line. The whole data set indicates a smooth increase to the higher kinetic energy values of about 9% around 50 eV above threshold. This behaviour can be well described qualitatively by the adiabatic transition model of Thomas, although the sudden limit value of this model seems to be reached too slowly and is, as a consequence of this, too high. Nevertheless, this strongly supports the idea that the strongest K-shell satellites are predominantly 'shake-up' in character, exhibiting a smooth transition to the sudden-limit intensity in the near-threshold region. Furthermore, other related phenomena, such as post-collision interaction and enhanced intensity of zero-kinetic-energy electrons above threshold, are observed and briefly discussed.

This includes discussion of domain structure, the magnetization process, microstructure, sample preparation, magnetostriction, effects of different chemical compositions on magnetic properties of the alloys, and possible applications of these materials. It has been found over recent years that there has been a steady improvement in material properties, both in terms of increased strain amplitude and reduction in variability from sample to sample. The material is now finding applications in magnetostrictive transducers, actuators and adaptive vibration control systems.

This structure is a variant of the helix-turn-helix motif, typified by catabolite activator protein. In the heat shock transcription factor, the first helix of the motif (alpha2) has an alpha-helical bulge and a proline-induced kink. The angle between the two helices of the motif (alpha2 and alpha3) is about 20-degrees smaller than the average for canonical helix-turn-helix proteins. Nevertheless, the relative positions of the first and third helices of the bundle (alpha1 and alpha3) are conserved. It is proposed here that the first helix of the three-helix bundle be considered a component of the helix-turn-helix motif. C1 UNIV CALIF BERKELEY,DEPT MOLEC & CELL BIOL,BERKELEY,CA 94720.

The reaction was studied at room temperature using the discharge flow technique with mass spectrometric detection of the reaction products. Measured product branching fractions at room temperature for production of N2O + H (D) were 0.8 +/- 0.4 for NH ((3) Sigma(-)) + NO and 0.87 +/- 0.17 for ND((3) Sigma(-)) + NO (l sigma statistical errors). Stationary points on the HNNO (2)A' potential energy surface were characterized using the Gaussian 2 ab initio method. The initial addition of NH((3) Sigma-) to NO on the (2)A' surface is predicted to proceed without a barrier to form trans-HNNO; reaction to produce the cis isomer is predicted to have a barrier of 2.9 kcal/mol. The cis- and trans-HNNO are predicted to be at -48.9 and -56.0 kcal/mol relative to the separated reactants. Transition states with energies of -25.3 and -17.9 kcal/mol were located for dissociation of the cis isomer into H + N2O and OH + N-2, respectively. The transition state for interconversion of the isomers was calculated to be at approximately -30.8 kcal/mol. The trans-HNNO was found to isomerize to the cis form before decomposing. The potential energy surface calculated explains the major features of the reaction. RP DURANT, JL (reprint author), SANDIA NATL LABS,COMBUST RES FACIL,LIVERMORE,CA 94551, USA.

Clearly defined surface composition was determined via LEIS (low-energy ion scattering). Electrocatalytic activities were measured by CO stripping voltammetry as well as by potentiostatic oxidation of adsorbed CO. It was found that the property of Ru atoms to nucleate oxygen-containing species at low potentials produced a strong enhancement in the catalytic activity of sputter-cleaned Pt-Ru alloy electrodes compared to pure Pt, thereby supporting the concept of the bifunctional character of the oxidation process of these alloys. A further synergistic effect of the alloy with a Ru surface composition of approximate to 50 atom % Ru was observed, with a catalytic shift in the CO electrooxidation current of -0.25 and -0.15 V compared to those of pure Pt and pure Ru surfaces, respectively. This synergism was attributed to a uniquely active state of OHads on Pt-Ru pair sites. The different electrocatalytic activities of sputter-cleaned versus annealed Pt-Ru alloy electrodes with essentially identical Ru surface compositions are discussed in terms of Ru clustering during annealing.

In parallel with geological and geochemical investigations, it is now possible to investigate the temporal and spatial pattern of volcanism at ocean ridges by dating young basalts using mass spectrometric uranium-series disequilibria methods8-11. Here we use U-238-Th-230 and U-235-Pa-231 ages for basalts to quantify the spatial extent of young volcanism and crustal accretion at 9-degrees 31' N on the East Pacific Rise. Most of the ages are younger than would be expected based on off-axis distance and spreading rate. We infer from these anomalously young ages that most of the dated basalts on the crestal plateau were erupted 0.5-2 km outside the axial summit caldera, with some volcanism occurring as far as 4 km off-axis. Melts erupted outside the axial summit caldera can have crustal residence times and magmatic supply systems that differ from those of axial lavas. C1 UNIV FLORIDA,DEPT GEOL,GAINESVILLE,FL 32611.

The samples studied were polycrystalline with the average grain size increasing from approximately 1 mu m on the substrate side to approximately 30 mu m on the growth surface for the thickest sample. Using time-resolved transient photoconductivity and charged-particle induced conductivity, the collection distance (d) that a free carrier drifts under the influence of an applied electric field was measured. Our data indicate that there is a gradient in the collection distance through the material. This gradient in electrical properties has implications for electronic uses of CVD diamond.

The irreversibility field H-r(T) (parallel to the c axis) was found to change approximately as L(0.13), where L is the effective dimension of the superconducting tape. Furthermore, it was found that the irreversibility line for a grain-aligned Bi2Sr2Ca2Cu3Ox specimen can be approximately reproduced by the extrapolation of this relation down to a grain size of a few tens of micrometers. The observed size effect could significantly obscure the real physical meaning of the irreversibility lines. In addition, this finding surprisingly indicated that the Bi2Sr2Ca2Cu2Ox/Ag tape and grain-aligned specimen may have similar flux line pinning strength. C1 NKT,RES CTR,DK-2605 BRONDBY,DENMARK.

We compare the FIRAS data to previous precise measurements of the cosmic microwave background spectrum and find a reasonable agreement.

The observed critical behaviour is significantly different to that observed with conventional neutron scattering techniques. Our analysis suggests that the critical scattering is composed of two components, the sharper of which may be related to the surface or be a result of long-range order nucleated by impurities.

Decrease of radius of gyration was observed under pseudo-first-order conditions with excess proteinases, which exhibited a monophasic timecourse. The rate constants were 0.5 +/- 0.1 s(-1) and 0.8 +/- 0.2 s(-1) for the reaction with chymotrypsin and trypsin, respectively. There was no concentration dependence of the observed rate constants. Therefore, the rate-limiting step of the gross conformational change was not the bimolecular encounter reaction between alpha(2)M and proteinases, which requires a new proposal of pre-trapping of proteinases before the gross conformational change.

By comparing these data with the BFF model, for which all remaining parameters were measured independently, it was determined that mu(e) = (7.5(-2.4)(+3.4))mu(f), where mu(f) was the viscosity of the fluid.

In a cavity, their emission and absorption rates may grow or shrink - and even diverge - but they nevertheless balance to yield the Planck distribution via Einstein's equilibrium method, (a careless application of which might produce spurious q-dependent distribution functions). This drives home the point that the black-body energy distribution is not a handle for distinguishing q-excitations from plain oscillators. A maximum cavity size is suggested by the inverse critical frequency of such emission/absorption rates at a given temperature, or a maximum temperature at a given frequency. To remedy fragmentation of opinion on the subject, we provide some discussion, context, and references. C1 ARGONNE NATL LAB,DIV HIGH ENERGY PHYS,ARGONNE,IL 60439.

Four, sometimes opposing, effects are identified, arising from the rear and imaginary parts of (i) the extended tails of the complex optical potential due to the halo, and (ii) the complex polarization potential arising from breakup. Semiclassical expressions are derived which embody the expected differences, and compared with fully quantal optical-model calculations. The cases of Li-11 and C-11 scattering from C-12 at E/A approximate to 60 MeV are examined. The net effect of the halo depends upon the details of the interactions, but we conclude that Li-11 does not exhibit greatly enhanced refraction compared to C-11, and that its elastic scattering cross sections are similar to, and may be smaller than, those for C-11, in agreement with preliminary analyses of the measurements.

Both adatoms and vacancies are created by incident ions. Above 370 degrees C, mutual annihilation of adatoms and vacancies formed during sputtering enables layerwise removal of Si without adatom island formation. The metastability of decorated antiphase boundaries is responsible for the formation and persistence of long, narrow islands and of rough step edges on sputtered surfaces annealed as high as 700 degrees C.

By comparing diffraction data with results of detailed simulations, the reconstruction is found to consist of alternate (100) and (010) facets propagating periodically along the [11(0) over bar] direction like an irregular ridge-and-valley grating, with (110) terraces completely absent. The irregularity is due to variation in facet sizes, and the mean separation is determined to be L = 6 lattice spacings. The validity of this model is supported by STM imaging results which confirm the structure obtained from the LEED-data analysis. C1 RENSSELAER POLYTECH INST,DEPT PHYS,TROY,NY 12180.

Annealing to 1400 K in a limited coverage range produces a phase with chemisorbed oxygen and a structure characterized by a sharp p(2 x 1) LEED pattern. AES and ion scattering evidence indicates that the oxygen coverage is about 0.8 to 1.0 ML and shows that this structure contains vacancies ordered into missing rows. Oxygen atoms are adsorbed near three-fold hollow sites which result from the vacancy formation. Oxygen is found to induce loss of Re from the first and second layers in a thermally activated place exchange with Mo atoms. The structural features found are discussed and compared with previous results from oxygen adsorption on Mo(001) and W(001) surfaces and the effect of oxygen on the component depth profile is explained on the basis structural and thermodynamic stability.

Experiments have shown that the surface symmetry is (1 x 1). We show that the simplest surface which is (1 x 1) and autocompensated has a single oxygen adatom per surface unit cell, located on the cell's mirror symmetry plane. The predicted relaxations of other surface atoms from their bulk positions are large enough to be detected by LEED analysis. This result demonstrates the power of the autocompensation principle, which straightforwardly shows that none of 63 possible truncated bulk structures should be stable, and points to the single-adatom stoichiometry.

The advantages compared to conventional techniques are good reproduceability, low cost and reduced risk of process failure. A focusing Ge(115) monochromator made from 24 wafer stacks was built for the high-resolution neutron powder diffractometer at the High Flux Beam Reactor at Brookhaven National Laboratory. Besides building ''classical'' monochromators for elastic neutron scattering experiments, individual wafers with a given peak reflectivity can be tilted with respect to each other to increase the reflected wavelength band Delta lambda/lambda. Such ''fanned'' arrays present a competitive alternative to monochromators using highly-oriented pyrolitic graphite (HOPG).

If applied to an L(2) wavepacket which overlaps the interaction, it yields either scattering-type (improper) eigenstates or proper bound eigenstates. For negative energies, the exact SDO yields zero away from an eigenvalue, and yields the energy eigenstate (times a constant) when E equals an eigenvalue. The finite orthogonal polynomial expansion of the SDO, acting on an L(2) wavepacket, yields approximately zero for E not equal to an eigenvalue, and becomes nonzero in the neighborhood of an eigenvalue.

Negative ion mass spectrometry revealed molybdenum carbide cluster ions with a stoichiometry MonC4n (n = 1 to 4). The MonC4n- (n = 2 to 4) ions are completely unreactive with NH3, H2O, and O2, suggesting structures in which the molybdenum atoms are unavailable for coordination to additional ligands. Collision-induced dissociation studies of these anions show the loss of MoC4 units as the main fragmentation pathway. This observation, together with the lack of addition reactions, provides a basis for structures in which a planar cluster of two, three, or four molybdenum atoms is surrounded by, and bonded to, carbon dimers.

Two decomposition pathways for COCl2 are possible: (1) COCl2 (+M) --> COCl + Cl (+M) and (2) COCl2 (+M) --> CO + Cl2 (+M). The branching ratios were observed to be 90.5% and 9.5%, respectively. Second-order analysis for the sum of (1) and (2) gave the rate expression k(d)/[Kr] = (8.0 +/- 3.8) X 10(-8) exp(-30549 +/- 766 K/T) cm3 molecule-1 s-1, with an error of +/- 35% at the one standard deviation level. This expression compares favorably to results from the decompositions of CH3Cl, CH2Cl2, and CC14 and provides evidence to suggest that the DELTAH-degrees10 is in the range 70-80 kcal mol-1. Theoretical analysis has also been applied to reaction 1 using Troe's semiempirical methods. The best overall fit is obtained with DELTAH-degrees10 = 74.5 +/- 1.0 kcal mol-I and DELTAE(down) = 1714 cm-1. This DELTAH-degrees10 implies DELTA(f)H-degrees (0 K) - -6.3 +/- 1.0 kcal mol-1 for COCl. Similar theoretical analysis for reaction 2 suggests a barrier height of 81.35 kcal mol-1.

The molecules, C5-C-10 linear, branched, and cyclic hydrocarbons, were studied by computer simulation using classical mechanical energy minimization and molecular dynamics (MD) methods. We held the atoms in the clay surface rigid, while the hydrocarbons were allowed complete flexibility both internally and in relationship to the clay. The atomic coordinates for the clay were developed from a model proposed for an Ascan smectite. We modeled the nonbonded atomic interactions between the clay surface and the hydrocarbons with a simple Lennard-Jones (LJ) potential. The main purpose of our investigation was to determine the sensitivity of the results to the LJ potential parameters. We thus used two sets of values, those from the mm2 force field and those of Hopfinger. To evaluate the usefulness of these potential sets, we compared the calculated enthalpies of adsorption to experimental values from gas chromatography retention studies. The results show that both sets of LJ potentials can represent the trend in the enthalpies of adsorption but give substantially different absolute values. We also find that the calculated trends are quite different if the data are taken from MD simulations of ensembles of molecules, rather than energy minimizations of individual molecules. In particular, the MD calculated values are almost-equal-to 5.3 kcal/mol less negative due to the explicit inclusion of temperature. There is still much work needed in developing nonbonded potentials for these types of systems. However, the results demonstrate the great utility of molecular modeling techniques for studying adsorbate-clay interactions. C1 PACIFIC NW LAB, MOLEC SCI RES CTR, RICHLAND, WA 99352 USA.

Both pore-saturating brines2 and interconnected carbon films3-5 have been proposed as conducting pathways, but their relative importance remains uncertain, and may vary from place to place6. So far, attempts to address this question in the laboratory have had to rely on samples of metamorphic rock collected from surface exposures7-10. Although these rocks almost certainly originated in the lower crust, chemical alteration during their transport to, and residence at, the surface is likely to have affected their conducting properties. Here we report conductivity data for pristine crustal rocks recovered from depths of up to 4.6 km in the KTB boreholes in southern Germany. Our results show that the electrical conductivity of accessory phases such as Fe-Ti oxides and sulphides can enhance, or even surpass, the high conductivity produced by saline fluids.

A rapid decrease of the energy dependence of this observable at 90 degrees CM is observed around 2.11 GeV kinetic energy. This agrees with the behavior of A(oonn) predicted on the basis of an exotic six-quark structure. The A(oonn) (90 degrees CM), together with the known differential cross section, allows the determination of the absolute value of the pure spin-singlet amplitude. The energy dependence of this amplitude shows a shoulder centered at 2.11 GeV, corresponding to a total mass of 2.735 GeV and an estimated width of 17 MeV.

Conversely, many hydrothermal systems exhibit varying degrees of apparent fluid-rock oxygen isotope disequilibrium (measured alpha(rock-water) not equal equilibrium alpha(rock-water)). A comparison of data from a variety of hydrothermal systems indicates that an increase in the degree of isotopic equilibration can be related, in a general way, to an increase in the temperature, salinity, and intensity of fracturing. This relationship is entirely consistent with calculations carried out for a simple closed-system model that estimates the fraction of isotope exchange between rock and fluid as a function of temperature, rock type, salinity of the fluid, grain size, water/rock ratio, and the rate of isotope exchange. The fact that many silicate-fluid reactions and their isotopic counterparts are fast leads us to conclude that observed variations in the degree of exchange may have resulted from local self-sealing of the fracture network prior to equilibration. The ability for fractures to remain open or to propagate, allowing continued fluid flow, may be the deciding factor in the attainment of isotopic equilibration.

The products of these reactions are L(1)CoOO(2+) and L(2)CoOO(2+), where L(1) = cyclam and L(2) = hexamethylcyclam. The pressure dependence of the equilibrium constant for the L(2) system was also evaluated, giving Delta V degrees = -22.0 +/- 0.4 mL mol(-1). The binding rate constants have Delta V double dagger = +0.4 +/- 0.5 mL mol(-1) (L(1)) and -4.7 +/- 0.3 mL mol(-1) (L(2)). The reverse reaction for L(2)CoOO(2+) has Delta V double dagger = +17.9 +/- 0.5 mL mol(-1). The volume profile is presented for the L(2) system, from which an interchange mechanism for substitution at Co(II) is proposed. Electron transfer is not significantly advanced at the transition state. The reverse reaction, release of dioxygen from the cobalt(III)-superoxo complex, has a large positive value of Delta V double dagger, consistent with the electron transfer preceding the partial dissociation of O-2.

The neutron powder diffraction refinement for Li5ReO6 confirms a recent single-cystal X-ray diffraction study: monoclinic, space group C2/m. This structure is retained by Li5ReO6 between 298 K and 10 K. The neutron powder diffraction refinement for Li4NpO5 confirms earlier X-ray powder diffraction results: tetragonal, space group I4/m, a = 6.698 angstrom, c = 4.415 angstrom. The lithium and oxygen positional parameters of L4NpO5 have been refined: coordination about Np is an extended octahedron, with each Np ion surrounded equatorially by four oxygen ions at 2.00 angstrom and axially by two oxygen ions at 2.21 angstrom. Li5NpO6 shows an X-ray powder pattern consistent with the original report, but the neutron diffraction data set could not be refined in terms of the originally proposed space group or any other plausible model structure.

The principal technical problem that limits device applications has been achieving controllable p-type doping. Molecular beam epitaxy assisted by a nitrogen ion beam produced p-type GaN when doped via ion implantation, diffusion, or coevaporation of Mg. Nearly intrinsic p-type material was also produced without intentional doping, exhibiting hole carrier concentrations of 5 X 10(11) cm-3 and hole mobilities of over 400 cm2/V/s at 250 K. This value for the hole mobility is an order of magnitude greater than previously reported. RP RUBIN, M (reprint author), LAWRENCE BERKELEY LAB,BERKELEY,CA 94720, USA.

The fields produced by the eddy currents are imaged with a spatial resolution of about 80 mum over a 100-mm2 sample area. With the sample and SQUID at 77 K, the microscope uses typical probing fields of 80 nT and can obtain simultaneously eddy current and static magnetic field images. At probing frequencies of 26-100 kHz, the system achieves a field sensitivity of about 7 pT Hz-1/2. C1 LAWRENCE BERKELEY LAB,DIV MAT SCI,BERKELEY,CA 94720.

The results of x-ray diffraction determinations of basal plane texture of Tl-1223 deposits prepared by spray pyrolysis are observed to depend on the size of the x-ray beam. Furthermore, most grain boundaries were found from transmission electron microscopy to have small misorientation angles. It is concluded that although overall the basal plane orientations are nearly random, there is a high degree of local texture indicative of colonies of similarly oriented grains. The spread in a-axis orientation within a colony is approximately 10-degrees-15-degrees. Intercolony conduction, it is suggested, may be enhanced by a percolative network of small-angle grain boundaries at colony interfaces. C1 GE CO,RES & DEV,SCHENECTADY,NY 12301.

We find that the coverage dependence of the core-level shift in the first layer is well correlated with the work function change. We suggest that these quantities are related through the coverage dependence of the alkali dipole moment and the position of the centroid of the alkali valence charge density. In order to confirm this relationship, we use a simple fitting procedure which is able to reproduce the work function changes from the core-level shifts for all three systems.

There is evidence for the formation of new Hg electronic states arising from Hg adatom hybridization and quantum-well states. These results, combined with the resonant photoemission, suggest that the overlayer undergoes a gradual non-metal-to-metal transition with increasing coverage and are similar to the change of the metallic properties observed in free Hg clusters with increasing size. The Hg band structure exhibits little evidence for strong interactions or hybridization with the W(110) substrate, in spite of layer by layer growth of the Hg overlayer, and superlattice periodicity.

The random-coil polymer was polystyrene (PS). The rodlike polymer was helical poly(gamma-stearyl alpha,L-glutamate), or PSLG, which aggregates end-to-end in toluene to produce long filaments. As PSLG is almost isorefractive with toluene, the scattering of PS can be measured in PSLG/toluene mixtures with almost no interference from PSLG. The apparent second virial coefficient of the PS component decreases rapidly with addition of the ''invisible'' rodlike polymer component, while the PS radius of gyration does not. A theta condition is reached at slightly more than 1% added PSLG. Although PSLG and PS probably have a disfavorable interaction parameter, enthalpic interactions are of secondary importance. This point was underscored by experiments involving the addition of 5% dodecane to binary PS/toluene solutions; the small, aliphatic solvent had virtually no effect. The reduction of the virial coefficient, but not the size, of the random-coil polymer in the presence of PSLG is due to the occupation of connected (and linearly correlated) space. Parallel effects were observed in the mutual diffusion coefficient of the coil component, which increased with PS concentration at low rod content but did the opposite when enough PSLG was added. Extrapolated to zero PS content, the mutual diffusion coefficient is expected to approach closely the self-diffusion of trace quantities of PS in the PSLG/toluene solution. So obtained, the self-diffusion coefficient decreased with added rodlike PSLG, but not as fast as the viscosity increased; thus, the Stokes-Einstein relationship was not obeyed by PS probes in PSLG/toluene solutions. Scaling arguments are presented for the dependence of the size of a random coil in the presence of rods and for the crossover from Stokes-Einstein diffusion of the coil to a reptative type of motion. The available data are not well suited to test these relationships, due to limitations in the matrix concentration imposed by polymer incompatibility.

The yield of singly strange particles as a function of negative particle multiplicity has been measured. Rapidity and transverse momentum distributions from events consistent with a maximum impact parameter of 9 fm are compared with the predictions of Fritiof 7.02, Venus 4.10 and RQMD 1.08. The comparison illustrates the importance of re-interactions of secondaries and suggests that additional physical processes are required to be incorporated into the event generators. The analysis of strange particle ratios indicates that strangeness phase space is not saturated in these collisions. C1 LAWRENCE BERKELEY LAB, MAILSTOP 50D, 1 CYCLOTRON RD, BERKELEY, CA 94720 USA.

The CERES spectrometer, has a novel design based on two Ping Imaging Cherenkov (RICH) counters, and it operates close to its design specifications. Data were recorded with 200 GeV/u sulfur beam and 450 GeV proton beam. The analysis is in progress. We have extracted first e+e--pairs samples for p+Be, p+Au and S+Au collisions. In addition other physics topics were addressed. Inclusive photon spectra were measured in S+Au interactions. No excess over known hadronic sources was found within our present systematic error of 11%. Results on high pt charged pion spectra are presented up to 4 GeV/c. We also studied the production of e+e--pairs in the strong electromagnetic fields of very peripheral S+Pt collisions. The data are well described by a first-order perturbative QED-calculation.

It now possible to study ultra-relativistic heavy ion collisions over a wide range of projectile and target masses. The data presented here are from the experiments E-866 and E-802. The first E-866 measurements [1] using the Au beam were made with existing E-802 spectrometer [2]. For E-866, an upgraded forward calorimeter has provided a hardware centrality trigger corresponding to E(ZCAL), less-than-or-equal-to 100 GeV, with the beam kinetic energy being E(BEAM) = 2108 GeV. Software cuts on E(ZCAL) were used to define roughly the upper 4% of the total cross section and referred to as central Au+Au collisions. Beside the statistical errors presented here, a systematic error of (10-15)% has to be applied for each result. RP GONIN, M (reprint author), BROOKHAVEN NATL LAB,DEPT PHYS,UPTON,NY 11973, USA.

In particular predictions from ARC for Au on Au at 11.6 GeV/c have proved to be remarkably accurate. Going to lower energies and inserting a phenomenological equation of state into the cascade should lead to information about the interesting region of high baryon density.

We estimate the size and nature of spatial structure in this phase, and show that at the lowest densities the quark matter forms droplets embedded in nuclear matter. At higher densities it can exhibit a variety of different geometries. This rich structure provides new mechanisms for glitches and cooling. Gross properties of these stars such as masses, radii and gravitational redshifts are compatible with observational constraints. C1 LAWRENCE BERKELEY LAB,DIV NUCL SCI,BERKELEY,CA 94720.

Using a second-level trigger to enhance the collection rate of rare events from Si+A collisions, it has been possible to achieve good statistics for processes with much smaller production cross-sections. This contribution focuses on four specific topics out of the broad range of physics addressed by E859; 1) The enhancement in the yield of K- relative to pions is almost identical to that found earlier for K+, 2) The dN/dy and inverse slope parameters of pBAR's have been measured with significantly higher statistics, 3) The ratio of LAMBDABAR over A production has been measured and the results suggest that a large fraction of the pBAR's from central Si+Au interactions may come from LAMBDABAR's, and 4) High statistics correlation measurements have been performed for pions, kaons, and protons and interesting differences in the derived source parameters axe found.

In agreement with previous measurements, an apparent power-law growth of moments with decreasing interval is observed down to deltaeta approximately 0.1. Experience with E(T) distributions suggests that fluctuations of multiplicity and transverse energy can be well described by Gamma or Negative Binomial Distributions (NBD) and excellent fits to NBD were obtained in all deltaeta bins. The k parameter of the NBD fit was found to increase linearly with the deltaeta interval, which due to the well known property of the NBD under convolution, indicates that the multiplicity distributions in adjacent bins of pseudorapidity deltaeta approximately 0.1 are largely statistically independent.

Pre-equilibrium gluon rescatterings are shown to have significant contributions to the charm production. In contrast to the gluon shadowing effect in the initial parton scattering, the enhancement of the final total open charm in the central region due to pre-equilibrium production could be used as a probe of the early dynamics of the partonic system.

These divergences originate from multiparticle intermediate states. The string amplitudes do not have the imaginary part required by unitarity. We give a prescription for defining string amplitudes that extends to all tachyon-free string theories. Explicit applications of our procedure are given at one-loop level for the Green-Schwarz and Neveu-Schwarz-Ramond theories. Our procedure is valid for higher loops also. However, only some simple features for this situation are explicitly discussed. C1 UNIV CALIF BERKELEY,DEPT PHYS,BERKELEY,CA 94720. LAWRENCE BERKELEY LAB,DIV PHYS,THEORET PHYS GRP,BERKELEY,CA 94720.

We consider a single generation of neutrinos with a Dirac mass mu and a Majorana mass M for the right-handed component. If M >> mu (standard hot dark matter corresponds to M = 0), then sterile neutrinos are produced via oscillations in the early Universe with energy density independent of M. However, M is crucial in determining the large scale structure of the Universe; for M approximately 100 eV, sterile neutrinos make an excellent warm dark matter candidate.

We model in simultaneously fusions from independent constituents and from the same constituent, both in a proton and in a large loosely bound nucleus of A approximately 200. In addition to the actual distributions at small x, we study the ratios of the distributions at an initial scale Q0 = 2 GeV, and show that a strong nuclear shadowing can follow from the modified QCD evolution.

This is shown through a Monte Carlo study of the decomposition kinetics of a bcc TiV alloy based on first-principles electronic structure calculations. Specifically, we predict a transient B32 ordering of the quenched-in solid solution before separation into Ti- and V-rich disordered phases. We discuss the requirements for such unusual behavior in relation to experiment, and compare Monte Carlo results for a 2D model system with mean-field predictions.

The ordering wave vector is (1/2 +/- delta, 0, 1/2) where delta = 0.110 +/- 0.003. The measured superlattice intensities are well described by the presence of a longitudinal spin density wave within the hexagonal basal plane, polarized along a*. The magnitude of the maximum ordered moment is found to be very small; mu(ord) = (0.24 +/- 0.10)mu(B). C1 ATOM ENERGY CANADA LTD,CHALK RIVER NUCL LABS,CHALK RIVER K0J 1J0,ONTARIO,CANADA.

Single molecules of rhodamine 6G are detected on a silica surface under ambient conditions using near-field scanning optical microscopy. Photobleaching of an individual molecule appears as an abrupt disappearance of fluorescence after seconds of constant excitation. Other reversible, upward and downward changes in fluorescence are observed, possibly due to reorientation of molecules on the surface. C1 LOS ALAMOS NATL LAB,DIV LIFE SCI,LOS ALAMOS,NM 87545.
