Transverse beam profiles on RHIC are measured with ionization profile monitors (IPMs). An IPM measures beam profiles by collecting the electrons liberated by residual gas ionization by the beam. The detector is placed in the gap of a dipole magnet to force the electrons to travel in straight lines from the beamline center to the collector. One IPM was tested and it measured the profiles of a single gold bunch containing 10(8) ions on consecutive turns. We show an example of one of these profiles giving transverse emittance. Several profiles are assembled into a mountain-range plot which shows betatron oscillations at injection. Finally, we use tomographic techniques to reconstruct the beam transverse phase space at two times in the early beam store. (C) 2000 Elsevier Science B.V. All rights reserved.

Two consecutive irradiations were performed for total fluences of 5.0 x 10(8) and 10.4 x 10(8) n/cm(2), with PSD tests performed after each irradiation. These irradiations degraded the energy resolution and line shapes; however, PSD corrections significantly restored the performance, even after severe damage. These PSD techniques delay and potentially eliminate, in some experimental situations, the need to anneal germanium detectors in damaging radiation environments, (C) 2000 Elsevier Science B.V.

Electron capture becomes dominated by capture from electron-positron pairs, projectile-ionization cross-sections saturate as the "maximum" impact parameter exceeds the Thomas-Fermi radius of a neutral target atom and the stopping power is reduced when the wavelength of the target electron with respect to the moving ion approaches nuclear size.

The trajectories of such channeled positrons can be manipulated to sample different spatial regions in the crystal. Here we report the first observations of channeling effects on in-flight annihilation radiation from positrons traversing a thin gold crystal. The channeling minimum yield for two-photon annihilation is shown to be significantly enhanced compared to single photon annihilation due to the selective interaction of well-channeled positrons with valence electrons in the interstitial regions of the crystal. Both classical and quantum calculation of annihilation yields are compared to the experimental data. (C) 2000 Elsevier Science B.V. All rights reserved.

We observed enhancements of both the fraction of ionized Ar18+ ions and the intensity of the de-excitation X-rays under the RCE condition. The n = 2 states of Ar17+ in the crystal are split into four energy levels due to spin-orbit interaction and Stark effect induced by the planar potential of the crystal. The intensities of the X-rays from the lower two levels were found to be smaller compared with those from the higher two levels, which is explained by the dominance of the 2s component not decaying via a single photon emission. The difference between the resonance profiles of the charge state and the X-ray reflects the nature of n = 2 states in the crystal field. (C) 2000 Elsevier Science B.V. All rights reserved.

In this transient region, projectiles may suffer energy loss different from the mean value. For gas targets, most of the relevant cross-sections and energy transfers can be determined separately by experiment. This allows one to relate these data to the stopping cross-section and to simulate the passage of ions through gas by Monte-Carlo techniques. For solid targets matter is worse, but a universal formalism how pre-equilibrium processes may be determined from transmission data is well documented by Sigmund [14 15]. In transmission experiments usually only these projectiles are analyzed that have missed the central region of the target atoms. It is, however, a matter of fact that projectiles passing closer to the nucleus are more likely to lose energy. In the case of thin targets these projectiles are deflected out of the detector acceptance leading to a reduction of the measured average energy loss. Hence, stopping data may be influenced by so-called impact parameter selection (IPS) according to the layout of the experiment. This IFS clearly acts also in the regime of pre-equilibrium stopping. Using Monte-Carlo simulation we studied to which extent in a typical transmission experiment energy loss is influenced by pre-equilibrium stopping and by IFS, respectively. For feasibility, instead of a solid target, we follow the trajectories through a dense gas target. We find that in an actual experiment with small detector opening angle the formalism to describe pre-equilibrium stopping has to include IFS. (C) 2000 Elsevier Science B.V. All rights reserved.

We present applications to the stripping of relativistic H- and the population dynamics of electronic substates of 13.6 MeV/u Ar17+ ions by transmission through carbon foils.

Room-temperature implantation of 2-10 x 10(16) He/cm(2) at 40 or 50 keV forms bubbles, but subsequent annealing at 250 degrees C or above leads to exfoliation of the implanted surface layer. The exfoliation appears related to the agglomeration of bubbles on dislocations at the back of the layer; evidence suggests these may be misfit, dislocations formed to relieve compressive stress in the implanted layer. Implantation of He at 150 degrees C produces similar results. whereas the He diffuses out of GaAs without forming cavities during implantation at 300 degrees C. However, implantations of immobile Ar followed by He at 400 degrees C produce extended defects with bubbles in the implanted layer: the He can be degassed by subsequent annealing at 400 degrees C to produce 1.5-3.5 nm cavities that are stable at this temperature. The same treatment applied to an In0.10Ga0.90As/GaAs heterostructure produces larger cavities preferentially located on dislocations at the interface, with only slight reduction in strain of the epitaxial layer. The microstructures of both GaAs and the heterostructure clearly demonstrate an attractive interaction between bubbles or cavities and dislocations. (C) 2000 Elsevier Science B.V.

Two of these are from estimates of the eta' mass, one from the residue of the hairpin diagram and the other from the topological susceptibility combined with the Witten-Veneziano formula. The other two determinations of delta are from measurement of virtual eta' loop effects in m(pi)(2) vs, quark mass and in the chiral behavior of the pseudoscalar decay constant. All of our results are consistent with delta = .080(15). The expected absence of quenched chiral logs in the axial-vector decay constant is also observed.

A simplified semiempirical model predicting fission gas release from UO2+x fuel to the fuel rod plenum as a function of stoichiometry excess x is developed to apply to the fuel of a defective light water reactor fuel rod in operation. An effective diffusion coefficient including a parabolic dependence of x is obtained based on existing data in the literature. The new diffusion coefficient is a composite expression of intrinsic, fission-enhanced, and nonstoichiometry-induced diffusion. The effective diffusion coefficient is incorporated into the Booth model to assess the time-dependent fractional fission gas release. The new model predictions are compared with existing data.

The test conditions were characteristic of a spent-fuel assembly during transport or horizontal dry storage. The assembly was configured with a pitch-to-diameter ratio of 1.33 and backfilled with pressurized helium or nitrogen. The backfill pressure was varied between 1 and 5 atm, while the assembly power was varied between 1 and 5 W per heater rod. The resulting data are presented in the form of Nusselt-Rayleigh number correlations, where the Nusselt number has been corrected fro thermal radiation using a numerical technique. The staggered-array data are compared to pervious data for a similar-pitch aligned rod array (a simulated boiling water reactor fuel assembly) to determine if convective heat transfer is enhanced or hindered in a staggered configuration. For the overall array, both the staggered and aligned configurations yield Nusselt-Rayleigh curves with a three-regime trend, which suggests distinct conduction and convection regimes separated by a transition regime. For lower Rayleigh number (<10(6)), representative of the conduction regime, the aligned-array Nusselt number is 10 to 12% higher than the corresponding staggered-array value. However, in the convection regime at higher Rayleigh numbers, the staggered-array Nusselt number slightly exceeds the aligned-array Nusselt number. This is attributed to the fact that the staggered array begins to transition into the convection regime at lower Rayleigh number than the aligned array. For both configurations, the slope of the Nusselt-Rayleigh curve in the convection regime suggests turbulent flow conditions. C1 Motorola Semicond Prod Sector, Austin, TX 78735 USA.

These spectroheliograms were recorded on specially fabricated XUV and FUV 70-mm Kodak film. Rocket launches of this instrument payload took place in 1991 (MSSTA I) and 1994 (MSSTA II) at the White Sands Missile Test Range in New Mexico, sponsored by the National Aeronautics and Space Administration (NASA) sounding rocket experiment program. Immediately prior to the 1994 launch, visible light focusing tests of each telescope were performed in situ using a 1951 standard Air Force high-resolution test target, to measure optical resolution performance. We determined that the MSSTA II telescopes performed at diffraction-limited resolutions down to 0.70 arcsec at visible wavelengths. Based on these measurements, we calculate an upper bound to the focusing errors that incorporate the sum of all uncorrelated system focus errors that affect resolution performance. Coupling these upper bound estimates with the in-band diffraction limits, surface scattering errors and payload pointing jitter, we demonstrate that 11 of 19 MSSTA II telescopes-having negligible figures of focus errors in comparison to the corresponding visible diffraction limits-performed at sub arcsecond resolution at their operational FUV/EUV/XUV wavelengths during flight. We estimate the in-band performance down to 0.14+/-0.08 arcsec. (C) 2000 Society of Photo-Optical Instrumentation Engineers.

We demonstrated this method by constructing a coiled amplifier using Yb-doped, double-clad fiber with a core diameter of 25 mu m and a numerical aperture of similar to 0.1 (V approximate to 7.4). When the amplifier was operated as an amplified-spontaneous-emission source, the output beam had an M-2 value of 1.09 +/- 0.09; when seeded at 1064 nm, the slope efficiency was similar to that of an uncoiled amplifier. This technique will permit scaling of pulsed fiber lasers and amplifiers to significantly higher pulse energies and peak powers and cw fiber sources to higher average powers while maintaining excellent beam quality.

A variety of cellular stresses including DNA damage, hypoxia, nucleotide depletion, viral infection, and cytokine-activated signaling pathways that transiently stabilize the p53 protein, cause it to accumulate in the nucleus, and activate it as a transcription factor. Activation leads either to growth arrest at the G(1)/S or G(2)/M transitions of the cell cycle or to apoptosis. The molecular mechanisms by which stabilization and activation occur are incompletely understood, but accumulating evidence points to roles for multiple posttranslational modifications in mediating these events through several potentially interacting but distinct pathways. Both the similar to 100 amino acid N-terminal and similar to 90 amino acid C-terminal domains are highly modified by phosphorylation and acetylation, whereas modifications to the central sequence-specific DNA binding domain have not been reported. Seven serines and one threonine in the first 46 residues of the transactivation domain and four to five serines in the carboxyl-terminal domain are now known to be phosphorylated, and Lys320 and Lys382 in the carboxyl-terminal domain (human p53) can be acetylated. Antibodies that recognize p53 only when it has been modified at specific sites have been developed by several laboratories, and studies with these have shown that most of the known posttranslational modifications are induced when cells are exposed to DNA-damaging agents. Exceptions are Ser378, which is reported to be constitutively phosphorylated, and Ser376, which is dephosphorylated in response to DNA damage. These recent results, coupled with biochemical and genetic studies, suggest that several amino-terminal phosphorylations can be important in stabilizing p53 in response to DNA damage and in directing acetylation at C-terminal sites. DNA damage-induced modifications to the C-terminus inhibit the ability of this domain to negatively regulate sequence-specific DNA binding either by inducing a conformational change in the protein or by inhibiting non-sequence-specific DNA binding by the C-terminus. C-terminal modifications also modulate the oligomerization state of p53, and may modulate nuclear import/export. Modifications in response to DNA damage to other components that interact with p53 may also be important. In most cases, clear roles for specific modifications, interactions among individual modifications, and the enzymes responsible for each modification remain to be defined. Nevertheless, the field appears poised for major advances in the understanding of the molecular mechanisms that regulate p53 function. (C) 2000 Editions scientifiques et medicales Elsevier SAS.

At sufficiently high point-defect concentrations, cascade regions are unstable; recombination of interstitial and vacancy point defects can occur together with the aggregation of point defects into clusters. These clusters can collapse into various types of dislocation loop and stacking-fault tetrahedra which are large enough to produce lattice strain fields that are visible under diffraction-contrast imaging in a transmission electron microscope. The kinetics which drive cascade formation and subsequent collapse are investigated by analysing the microstructure produced in situ by low-fluence 100 keV Kr-ion irradiations of fee Cu over a wide temperature range (18-873 K). The product microstructures are characterized by quantitative measurements of the yields of collapsed point-defect clusters. In addition, their stabilities, lifetimes and size distributions are also examined. Defect yields are demonstrated unequivocally to be temperature dependent, remaining approximately constant up to lattice temperatures of 573 K and then abruptly decreasing with increasing temperature. This drop in yield is not caused by defect loss during or following ion irradiation. It rather reflects a decrease in the probability of cascade collapse which can be explained by a thermal spike effect. C1 Argonne Natl Lab, Div Mat Sci, Argonne, IL 60439 USA.

We measured the CCEs of three single diodes previously irradiated with different neutron fluences. The current-voltage characteristic were measured at 300 and 77 K, showing that the low-temperature operation considerably decreases the steady-state current. This is also the case when a forward voltage bias is applied, which then becomes a suitable option. At 77 K, in the case of samples irradiated with 5 x 10(14) neutrons cm(-2), the CCE is completely recovered. A third sample irradiated with 2 x 10(15) neutrons cm(-2) shows a 60% CCE at 250 V forward bias. C1 Ist Nazl Fis Nucl, I-80125 Naples, Italy. Brunel Univ, Uxbridge UB8 3PH, Middx, England.

The partition function and the zero-field magnetic susceptibility are readily shown to adopt their classical forms with increasing s. The behavior of the spin autocorrelation function (ACF) is more subtle. Unlike the classical Heisenberg trimer where the ACF approaches a unique non-zero limit for long times, for the quantum trimer the ACF is periodic in time. We present exact values of the time average over one period of the quantum trimer for s less than or equal to 7 and for infinite temperature. These averages differ from the long-time limit, (9/40)ln 3 (7/30), of the corresponding classical trimer by terms of order 1/s(2). However, upon applying the Levin u-sequence acceleration method to our quantum results we can reproduce the classical value to six significant figures. (C) 2000 Elsevier Science B.V.

The formalism is then extended to the case of electrons traveling parallel to a homogeneous slab of finite thickness in which either ordered or disordered collections of polarizable spheres are embedded. For an ordered system in which the spheres are in a cubic array, the calculated energy-loss spectra are compared with those of an alternative theory. For a slab with disordered collections of spheres we find the energy-loss spectra using the recursive Green's function method and compare our results with the available experimental data as well as with an extension of the semiclassical-infinite-barrier (SCIB) model. Finally, we discuss the relevance of our work as well as trends for future research. (C) 2000 Elsevier Science B.V. All rights reserved.

The 25-nm thick NGO buffer layer was dip-coated onto the STO single crystal from a solution of metal methoxyethoxides in 2-methoxyethanol. Pulsed laser deposition (PLD) was used to grow a 250-nm-thick YBCO film on the NGO. The epitaxial relationships are cube-on-cube throughout the structure when the pseudo cubic and pseudo tetragonal unit cells are used to describe the NGO and YBCO crystal structures, respectively: (001) YBCO // (001) NGO // (001) STO and [100] YBCO // [100] NGO // [100] STO. High resolution scanning electron microscopy (SEM) of the bare NGO surface revealed similar to 40 nm diameter pinholes with number density of similar to 2 x 10(13) m(-2), corresponding to an area Traction coverage of 2.5%, in an otherwise featureless surface. Cross-sectional transmission electron microscopy (TEM) showed that these pinholes penetrate to the STO; otherwise the NGO layer was uniformly thick to within approximately +/-5 nm and defect free. The X-ray diffraction phi- and omega-scans indicated that the YBCO film was highly oriented with a full-width-half maximum peak breadth of 1.14 degrees for in-plane and 0.46 degrees for out-of-plane alignment, respectively. The film contained sparse a-axis oriented grains, an appreciable density of (001) stacking faults and apparently insulating second phase precipitates of the type that typically litter the surface of PLD films. All of these defects are typical of YBCO thin films. High-resolution cross-sectional TEM images indicate that no chemical reaction occurs at the YBCO/NGO interface. (C) 2000 Elsevier Science B.V.

These spectra have been analyzed to obtain vibrational spacings, vibrational intensities, and the lifetime, tau, of the carbon 1 s core-hole state. Theoretical calculation of the lifetime width, (h) over bar h/tau, using a one-center model, which assumes that only the valence electrons localized on the atom with the core hole can participate in Auger deexcitation of the cure hole, predicts a value of 66 meV, considerably smaller than that predicted for CH4 (96 meV). Experimental measurements indicate, however, that the CO2 carbon 1 s width is, in fact, much larger than expected-99+/-2 meV-and is approximately the same as that found experimentally for CH4 (95+/-2 meV). This result indicates that valence electrons on the oxygen atoms may play a role in the Anger decay the carbon Is core hole in CO2, and, hence, that a multicenter model may be necessary to describe the Auger process.

We recently reported the results of an experiment using a novel two-foil method to measure the 9.5-psec lifetime of the 2 P-3(2) level in heliumlike krypton. We describe hen the results of an extension of that work in which we measured the time evolution of the N greater than or equal to 2 excited state population between the foils by observing the dependence upon foil separation of the charge-state distributions emerging from the second foil. The results are consistent with the well-known power-law dependence of Rydberg-fed atomic transitions observed in beam-foil studies, but probe a much shorter time scale than has hitherto been accessible.

This quantity was obtained from angular distribution measurements of the N4,5O2,3O2,3 Auger lines after ionization of free atoms by monochromatized synchrotron radiation of 80-250 eV photon energy. The data show a minimum of the alignment parameter in the Cooper minimum of the 4d photoionization cross section, which proves the vanishing of the outgoing epsilon f electron wave. Furthermore, the intrinsic parameters for all lines in this Auger group were determined and are compared with previous experiments and calculations.

This tripod linkage is an extension of the standard laser-induced continuum structure (LICS), which involves two discrete states and two lasers. We show that in the tripod scheme, there exist two population napping conditions; in some case. these conditions are easier to satisfy than the single trapping condition in a two-state LICS. Depending on the pulse timing, various effects can be observed. We derive some basic properties of the tripod scheme, such as the solution for coincident pulses, the behavior of the system in the adiabatic limit for delayed pulses, the conditions for no ionization and for maximal ionization, and the optimal conditions for population transfer between the discrete states via the continuum. In the case when one of the discrete states is strongly coupled to the continuum, the population dynamics reduces to a standard two-state LICS problem (involving the other two states) with modified parameters; this provides the opportunity to customize the parameters of a given two-state LICS system.

The proton-spin lattice relaxation rate 1/T-1, as a function of the temperature T and external magnetic field B, provides a very useful probe of the dynamical behavior of the four Cr+3 (spins s=3/2) paramagnetic ions which are ferromagnetically coupled via isotropic Heisenberg exchange interaction. From our derived formulas for the two-ion time correlation functions, we find that 1/T-1 may be expressed as a function of the single scaling variable mu(B)B/(k(B)T), where mu(B) is the Bohr magneton and k(B) is Boltzmann's constant, for the regime of our measurements. Our experimental data are in good agreement with this prediction and our derived form of the scaling function. C1 Iowa State Univ Sci & Technol, Ames Lab, Ames, IA 50011 USA.

Recent synchrotron x-ray powder diffraction measurements by Noheda et al. [Appl. Phys. Lett. 74, 2059 (1999)] have revealed a monoclinic phase between the previously established tetragonal and rhombohedral regions. In the present work we describe a Rietveld analysis of the detailed structure of the tetragonal acid monoclinic PZT phases on a sample with x = 0.48 for which the lattice parameters are, respectively, a(1) = 4.044 Angstrom, c(t) = 4.138 Angstrom, at 325 K, and a(m) = 5.721 Angstrom, b(m) = 5.708 Angstrom, c(m) = 4.138 Angstrom, beta = 90.496 degrees, at 20 K. In the tetragonal phase the shifts of the atoms along the polar [001] direction are similar to those in PbTiO3 but the refinement indicates that there are, in addition, local disordered shifts of the Pb atoms of similar to 0.2 Angstrom perpendicular to the polar axis. The monoclinic structure can be viewed as a condensation along one of the (110) directions of the local displacements present in the tetragonal phase. It equally well corresponds to a freezing-out of the local displacements along one of the (100) directions recently reported by Corker et al.[J. Phys.: Condens. Matter 10, 6251 (1998)] for rhombohedral PZT. The monoclinic structure therefore provides a microscopic picture of the MPB region in which one of the ''locally'' monoclinic phases in the "average" rhombohedral or tetragonal structures freezes out, and thus represents a bridge between these two phases.

The Gibbs free energy function is shown to reproduce the known equation of state properties of carbon up to pressures of 600 GPa (6 MBar) and temperatures of 15 000 K. Recent experiments on graphite melting suggest the presence of a first-order liquid-liquid phase transition at roughly 6 GPa. We show that such a transition is consistent with shock compression data at higher pressures. We reanalyze experiments on the diamond-liquid melting line with our equation of state. Our analysis suggests that the diamond-liquid melting line may have a more positive slope as a function of pressure than previously estimated. A maximum in the diamond melting line is predicted by the model, in agreement with recent nb initio simulations. C1 Univ Calif Lawrence Livermore Natl Lab, Livermore, CA 94551 USA.

Strikingly similar behaviors are found for both phases despite the OG's underlying crystal (bcc) lattice. Such similarity, which is also revealed in dielectric spectroscopy and inelastic neutron scattering measurements, suggests whole molecule small-angle librations as a common microscopic origin for a wide variety of ''glassy'' phenomena.

(1) Streaks of diffuse scattering along the reciprocal lines MRM were found to originate from dynamically correlated rotations of oxygen-octahedra within the (0 0 1) layer and uncorrelated rotation between the layers; when temperature is lowered to the transition temperature T-c congruent to 103 K, the crystal structure condenses into thin plates of antiphase domains in every orientational variant. (2) Diffuse scattering around the R point, due to the Gamma(25) phonon mode, becomes weaker and broader with an increase in temperature and is even detectable at 700 K. (3) Sheets of diffuse scattering in the reciprocal X-Gamma-X-M-X plane result from the correlated movements of atomic chains along the [0 0 1] direction. Structural models are proposed to interpret these diffuse scatterings. C1 Brookhaven Natl Lab, Dept Appl Sci, Upton, NY 11973 USA. Wuhan Univ, Dept Phys, Wuhan 430072, Peoples R China.

It is found that for temperatures below the bulk Neel temperature a magnetically disordered region exists at the surface, and is separated from the magnetically ordered bulk by a diffuse magnetic interface. The width of the magnetic interface is temperature dependent, and appears to diverge as the sample temperature approaches the bulk Neel temperature. In contrast to the bulk, which exhibits a discontinuous magnetic ordering transition, the surface layers order continuously. These results are shown to be qualitatively consistent with the theory of surface induced disorder. C1 Univ Maryland Baltimore Cty, Dept Phys, Baltimore, MD 21250 USA.

We start from the general Keldysh-Nambu-Gor' kov Green's functions in the quasiclassical approximation and represent them in terms of 2X2 spin-matrix coherence functions and distribution functions for particle-type and hole-type excitations. The resulting transport equations for the distribution functions may be interpreted as a generalization to the superconducting state of Landau's transport equation for the normal Fermi liquid of conduction electrons. The equations are well suited for numerical simulations of dynamical phenomena. rising our formulation we solve an open problem in quasiclassical theory of superconductivity, the derivation of an explicit representation of Zaitsev's nonlinear boundary conditions (A. V. Zaitsev, Zh. Eksp. Teor. Fit. 86, 1742 (1984) [Sov. Phys. JETP 59, 1015 (1984)]; A. L. Shelankov, Fiz. Tverd. Tela (Leningrad) 26, 1615 (1984) [Sov. Phys. Solid State 26, 981 (1984)]) at surfaces and interfaces. These boundary conditions include nonequilibrium phenomena and spin singlet and triplet unconventional pairing. We eliminate spurious solutions as well as numerical stability problems present in the original formulation. Finally, we formulate the Andreev scattering problem at interfaces in terms of the introduced distribution functions and present a theoretical analysis for the study of time reversal symmetry breaking states in unconventional superconductors via Andreev spectroscopy experiments at nomal-metal-superconductor interfaces with finite transmission. We include impurity scattering self-consistently. C1 Northwestern Univ, Dept Phys & Astron, Evanston, IL 60208 USA.

It is shown that if the three tricrystal arms are conventional junctions, a one-flux-quantum phi(0) vortex at or near the intersection has lower energy than one far from the intersection. If the largest Josephson length exceeds the sum of the other two, the tricrystal ceases to be a pinning site. If one of the tricrystal arms is a pi junction, a theta(0)/2 vortex at the intersection is the ground state of the system, and an even number of phi(0)/2 vortices is forbidden, whereas 3 phi(0)/2 and 5 phi(0)/2 correspond to possible but, in general, metastable states. For certain combinations of Josephson lengths, the 3 phi(0)/2 state has lower energy than the combined energy of the phi(0)/2 vortex at the tricrystal joint and phi(0) vortex far from the joint. Conditions are discussed under which the 3 phi(0)/2 vortex can be observed. C1 Iowa State Univ, Ames Lab, Ames, IA 50011 USA. Iowa State Univ, Dept Phys & Astron, Ames, IA 50011 USA.

Below T-c, the data also determine the inarbilayer magnetic exchange constant, which is reasonable with respect to recent spin-wave data, and the magnetocrystalline anisotropy. For c-axis fields, a mixed AF and spin-flop state (similar to the intermediate state of type-I superconductors) is a rigorous prediction of the data and modeling.

In spite of the large differences in the Curie temperatures (Tc's) of different manganites, their low-temperature spin waves have very similar dispersions with the zone-boundary magnon softening and broadening that cannot be explained by the canonical double exchange mechanism. From the wave-vector dependence of the magnon lifetime effects and its correlation with the dispersions of the optical-phonon modes, we argue that a strong magnetoelastic (magnon-phonon) coupling is responsible for the observed low-temperature anomalous spin dynamical behavior of the manganites.

For the uniform chain (alpha=1), the high-accuracy chi*(t) and C(t) Bethe ansatz data of Klumper and Johnston (unpublished) are shown to agree very well at low t with the respective exact theoretical low-t logarithmic correction predictions of Lukyanov [Nucl. Phys. B 522, 533 (1998)]. Accurate (similar to 10(-7)) independent empirical fits to the respective data are obtained over t ranges spanning 25 orders of magnitude, 5X10(-25)less than or equal to t less than or equal to 5, which contain extrapolations to the respective exact t=0 limits. The infinite temperature entropy calculated using our C(t) fit function is within 8 parts in 10(8) of the exact value In 2. Quantum Monte Carlo (QMC) simulations and transfer-matrix density-matrix renormalization group (TMRG) calculations of chi*(alpha,t) are presented for 0.002 less than or equal to t less than or equal to 10 and 0.05 less than or equal to alpha less than or equal to 1, and an accurate (2X10(-4)) two-dimensional (alpha,t) fit to the combined data is obtained for 0.01 less than or equal to t less than or equal to 10 and 0 less than or equal to alpha less than or equal to 1. From the low-t TMRG data, the spin gap a(rr) is extracted for 0.8 less than or equal to alpha less than or equal to 0.995 and compared with previous results, and a fit function is Formulated for 0 less than or equal to alpha less than or equal to 1 by combining these data with literature data. We infer from our data that the asymptotic critical regime near the uniform chain limit is only entered for alpha greater than or similar to 0.99. We examine in detail the theoretical predictions of Bulaevskii [Sov. Phys. Solid State 11, 921 (1969)], for chi*(alpha,t) and compare them with our results. To illustrate the application and utility of our theoretical results, we model our experimental chi(T) and specific heat C-p(T) data for NaV2O5 single crystals in detail. The chi(T) data above the spin dimerization temperature T(c)approximate to 34 K are not, in quantitative agreement with the prediction for the S=1/2 uniform Heisenberg chain, but can be explained if there is a moderate ferromagnetic interchain coupling and/or if J changes with T. Fitting the chi(T) data using our chi*(alpha,t) fit function, we obtain the sample-dependent spin gap and range Delta(T=0)/k(B)=103(2) K, alternation parameter delta(0)=(1-alpha)/(1+alpha)=0.034(6) and average exchange constant J(0)/k(B)=640(80) K. The delta(T) and Delta(T) are derived from the data. A spin pseudogap with magnitude approximate to 0.4 Delta(0) is consistently Found just above T-c, which decreases with increasing temperature. From our CP(T) measurements on two crystals, we infer that the magnetic specific heat at low temperatures T less than or similar to 15 K is too small to be resolved experimentally, and that the spin entropy at T-c is too small to account for the entropy of the transition. A quantitative analysis indicates that at T-c, at least 77% of the entropy change due to the transition at T-c and associated order parameter fluctuations arise from the lattice and/or charge degrees of freedom and less than 23% from the spin degrees of freedom.

Utilizing the well-established oscillatory interlayer exchange coupling in Fe/Cr, we have constructed [Fe/Cr](AF)/Cr/[Fe/Cr](F) double superlattices where Fe/Cr superlattices with appropriate Cr-spacer thickness represent the F and the AF. The double superlattices are (211)-oriented epitaxial films sputter grown on single-crystal MgO(110) substrates. The AF/F interface is coherent compared to conventional exchange-bias interfaces consisting of dissimilar AF and F phases. Magnetization results show that AF/F exchange coupling affects the nucleation of reverse magnetic domains, and that the magnitude of the exchange-bias field is given directly by the classic formula for collinear spin structures. The collinear spin distribution is confirmed by polarized neutron reflectivity. C1 Argonne Natl Lab, Argonne, IL 60439 USA.

After giving qualitative arguments for this effect, we present more quantitative calculations based on the Bogoliubov-de Gennes equation. Experimental observations of the effects of Andreev reflections above T-c-such as an enhanced tunneling conductance below the gap along the copper oxide plane-could provide unambiguous evidence for the preformed pairs in the pseudogap state.

Small peaks labeled A(1)-A(3) are observed which correspond to 1s-3d dipole transitions, made weakly allowed via a hybridization of Mn 4p states with Mn 3d states on neighboring atoms. Adjusting the parameters in a local spin-density approximation calculation to approximately match the experimental A(1)-A(2) Splitting yields U = 4 eV and J(H) = 0.7 eV. For colossal magnetoresistance samples, A(1) decreases with T while A(2) increases with T below T-c, which shows that the 3d bands change significantly as T moves through T-c. There are also small changes in the shape of the main edge (1s-4p transitions). C1 Univ Calif Santa Cruz, Dept Phys, Santa Cruz, CA 95064 USA.

Using lattice dynamic models based on first-principles calculations, we address the most popular microscopic mechanism, reduction via rattling ions. The model withstands inelastic neutron scattering and specific-heat measurements, and refutes hypotheses of an anharmonic RE potential and of two distinct localized RE vibrations of disparate frequencies. It does indicate a strong hybridization between bare La vibrations and certain Sb-like phonon branches, suggesting anharmonic scattering by harmonic RE motions as an important mechanism for suppression of heat conductivity.

A strong peak in the La-139 spin-lattice relaxation rate observed in the spin ordered state is well described by the BPP mechanism [Bloembergen, Purcell, and Pound, Phys.

Pressure induces segregation into antiferromagnetic electron-rich and ferromagnetic electron-poor Mn2O7 layers. With increasing pressure, the ferromagnetic majority phase exhibits contraction of the apical (Mn-O) bond and spin reorientation from the c axis to the basal plane at a critical pressure P-c(6 less than or equal to P(c)less than or equal to 7 kbar). The phase segregation appears to reflect a first-order inversion of the exchange coupling between ferromagnetic Mn2O7 layers. C1 Univ Texas, Texas Mat Inst, Austin, TX 78712 USA.

From the EC decays of Md-255 and Md-256, levels in Fm-255 and Fm-256 were deduced. Favored alpha decay of Md-255 was found to populate the 7/2(-)[514] single-particle state in Es-251, thus establishing the 7/2(-)[514] as the Md-255 ground state. Several gamma rays were observed in the Md-256 alpha-gamma coincidence spectrum. Fm-256 is the heaviest nucleus in which excited intrinsic states have been identified.

Light fragments at beam rapidity are measured for the first time at AGS energies. Beam rapidity deuteron and He-4 yields and transverse slope parameters are found to be strongly dependent on the impact parameter, and the shape of the deuteron spectra is not consistent with that expected for a simple thermal distribution. The deuteron yields relative to proton yields are analyzed in terms of a simple coalescence model. While results indicate an increase in source size compared to collisions of lighter systems at the same energy, they are inconsistent with a simple coalescence model reflected by a rapidity dependence of the coalescence parameter B-d. A new approach utilizing an expanding thermalized source combined with a coalescence code is developed for studying deuteron formation in heavy-ion collisions. The strong dependence of deuteron yields on collective motion implies that deuteron yields relative to those of protons can be used for constraining source parameters.

The bands were given configuration assignments based on their B(M1)\B(E2) ratios (Eor the strongly coupled bands), aligned angular momentum, observed band crossings, and signature splitting. Several quasiparticle alignments were observed in the bands and compared with predictions from the cranked shell model. Three-band mixing calculations were performed in order to interpret the low-spin interaction observed in the [411]1/2 band. An examination of the signature splitting for the [541]1/2 bands in (129),(131),Nd-133 revealed information regarding the parentage of the orbital as well as a signature inversion at higher spin.

When ground state correlations are included with an open p shell the predictions of the calculations are in reasonable agreement with most of the experimental results for these reactions. Woods-Saxon radial wave functions are used, with their asymptotic forms matched to the experimental separation energies for bound states, and matched to a binding energy of 0.01 MeV for unbound states.

Moving from central to peripheral collisions the measured charge distributions develop progressively according to a power law which can be fitted, within errors, by a single tau exponent independently of the bombarding energy except for the data at 250A MeV. In addition, the location of the maximum in the individual yields of different charged fragments, for a given beam energy, shifts towards lower multiplicity as the fragment charge increases from Z=3 to Z=7. This trend is common to ail six measured beam energies. Moments of charge distribution are also reported. The universal features observed in the present Au + Au data are consistent with previous experimental findings in the Au + C multifragmentation reaction at 1A GeV.

Only a certain class of nuclear interactions, however, such as pairing and quadrupole, is free of the numerical noise known as the sign problem. This paper presents sum rules that relate the sign problem to the J = 0 pairing matrix elements, thus illuminating the extrapolation procedure routinely use for realistic shell-model interactions.

The present data expand considerably the level scheme of this nucleus. A new collective structure has been identified and the known bands have been extended to higher spins. Firm spin and parity assignments have been made to many levels. Of particular interest are the negative parity bands which are interpreted in terms of structures associated with octupole vibrations crossed at moderate spin by two-quasiparticle excitations. The systematics of the alpha-decay reduced widths in Pt nuclei has also been investigated. The differences of a factor of about 2 between the widths for the odd- and the even-A isotopes is attributed to changes in neutron pairing associated with the blocking effect. The trend is reproduced in calculations based on the Lipkin-Nogami pairing model. C1 Argonne Natl Lab, Div Phys, Argonne, IL 60439 USA. Purdue Univ, Dept Chem, W Lafayette, IN 47907 USA.

SO PHYSICAL REVIEW C LA English DT Article ID PROTON-RICH NUCLEI; T=0 AB The binding energies of even-even and odd-odd N = Z nuclei are compared. After correcting for the symmetry energy we find that the lowest T = 1 state in odd-odd N = Z nuclei is as bound as the ground state in the neighboring even-even nucleus, thus providing evidence for isovector np pairing. However, T = 0 states in add-odd N = Z nuclei are several MeV less bound than the even-even ground states. We associate this difference with the T = 1 pair gap and conclude from the analysis of binding energy differences and blocking arguments that there is no evidence for an isoscalar (deuteronlike) pair condensate in N = Z nuclei.

Ln addition, some drip-line nuclei develop very extended halo structures. The neutron halo is a threshold effect; it appears when the valence neutrons occupy weakly bound orbits. In this study, nuclear skins and halos an analyzed within the self consistent Skyrme-Hartree-Fock-Bogoliubov and relativistic Hartree-Bogoliubov theories for spherical shapes. It is demonstrated that skins, halos, and surface thickness can be analyzed in a model-independent way in terms of nucleonic density form factors. Such an analysis allows for defining a quantitative measure of the halo size. The systematic behavior of skins, halos, and surface thickness in even-even nuclei is discussed.

We have devoted a large effort to the measurements of gamma gamma-coincidence spectra in the broad energy interval 50-6243 keV. From these data and those of previous studies, the level scheme has been developed containing levels grouped into 23 rotational bands below 1 MeV. Of these, six bands are new and several others, known previously, have been modified and expanded based upon our experimental data. In all, 32 new levels have been identified. Of particular note has been the identification of two rotational bands whose underlying structure consists of gamma-vibrational states built upon the two lowest energy quasiparticle states in Ho-166. Two new Gallagher-Moszkowski matrix elements were determined: E-GM(p7/2(-)[523]+/-n5/2(-)[523]) = - 108.5 keV and E-GM{(p7/2(-)[523]+/-n7/2(+)[633])+/-Q(22)} = + 138.2 keV. The resultant level scheme is in good agreement with semiempirical and quasiparticle phonon models where residual interactions have been taken into account. Suggestions are given for further experimentation on Ho-166 level structure using existing technology. C1 Nucl Res Ctr, LV-2169 Salaspils, Latvia. Tech Univ Munich, D-85748 Garching, Germany.

A rotational-like cascade of seven transitions is established down to the band head with probable spin and parity (13/2(+)). Unlike in the adjacent odd-mass T1 nuclei, prompt gamma decay from the yrast band to a lower lying weakly deformed (oblate) structure is not observed. These features are consistent with the predicted drop of the prolate band head in (183)T1 compared to (185)T1. The implications for the prolate energy minimum in odd-mass T1 nuclei at the neutron (i)13/2 midshell (N = 103) are discussed. C1 Univ Tennessee, Dept Phys, Knoxville, TN 37996 USA.

The mass-yield distribution of the fission fragments is highly asymmetric. The average pre-neutron emission total kinetic energy of the fragments was measured to be 183+/-18 MeV. Based on the ratio of the measured number of fission events to the measured number of cu decays from the electron-capture daughter Cf-242 (100% alpha branch), the probability of delayed fission was determined to be 0.006+/-0.002. This value for the delayed fission probability fits the experimental trend of increasing delayed fission probability with increasing Q value for electron capture.

A total of 36 p-wave neutron resonances were studied in In-115, and statistically significant asymmetries were observed for nine cases. An analysis treating the PNC matrix elements as random variables yields a weak matrix element of M = (0.67(-0.12)(+0.16)) meV and a weak spreading width of Gamma(w) = (1.30(-0.43)(+0.76)) x 10(-7) eV.

The differential decay curve method in coincidence mode was employed to derive lifetimes for six states in Ba-129 and twelve states in Ba-130. The resulting B(E2) Values are compared with triaxial rotor plus particle calculations for Ba-129 and, in Ba-130, to the predictions of the general collective model, the interacting boson model, as well as to the symmetric and asymmetric rotor models. In Ba-130, the transitional quadrupole moment in the ground state hand is remarkably constant before and after the backbend. With this data the two-quasiparticle negative parity band in Ba-130 was confirmed to be based on a pi(h(11/2)xd(5/2)/g(7/2)) configuration. C1 Univ Cologne, Inst Kernphys, D-50937 Cologne, Germany.

Gamma rays were detected with Gammasphere. and evaporated alphas and protons were detected with the Microball. The level scheme has been extended, and angular distributions of many of the transitions have been measured. A portion of the data was taken using a backed target, allowing lifetime measurements. No evidence for band termination was found in the spin range studied, but a cranking model analysis indicates possible shape evolution at higher spin. C1 Univ Pittsburgh, Pittsburgh, PA 15260 USA.

The Gamow factor needs to be modified when the magnitude of the effective coupling constant increases or when the velocity increases. For the production of a pair of particles under their mutual Coulomb-type interaction, we obtain the modification of the Gamow factor in terms of the overlap of the Feynman amplitude with the relativistic wave function of the two particles. As a first example, we study the modification of the Gamow factor for the production of two bosons. The modification is substantial when the coupling constant is large.

D LA English DT Article ID CTEQ PARTON DISTRIBUTIONS; CERN PBARP COLLIDER; YAN K-FACTOR; ROOT-S=1.8 TEV; P(P)OVER-BAR COLLISIONS; GAMMA COUPLINGS; CROSS-SECTIONS; E(+)E(-) INTERACTIONS; TRANSVERSE-MOMENTUM; PAIR-PRODUCTION AB We report on measurements on inclusive cross sections times branching fractions into electrons for W and Z bosons produced in p (p) over bar collisions at root s = 1.8 TeV. From an integrated luminosity of 84.5 pb(-1) recorded in 1994-1995 using the D empty set detector at the Fermilab Tevatron, we determine sigma(p (p) over bar--> W + X) x B(W-->e nu) = 2310 +/- 10(stat) +/- 50(syst) +/- 100(lum)pb and sigma(p (p) over bar-->Z + X) x B(Z-->ee)=221+/-3(stat)+/-4(syst)+/-10(lum)pb. From these, we derive sigma(p (p) over bar-->W + X) x B(N-->e nu)/sigma(p (p) over bar-->Z + X) x B(Z-->ee) = 10.43+/-0.15(stat) +/- 0.20(syst) +/- 0.10(NLO), B(W-->e nu) = 0.1044+/-0.0015(stat)+/-0.0020(syst)+/-0.0017(theory)+/-0.0010(NLO). and Gamma(w) = 2169 +/- 0.03 l(stat) +/- 0.042(syst) +/- 0.041(theory)+/- 0.022(NLO)GeV. We use the latter to set a 95% confidence level upper limit on the partial decay width of the W boson into nonstandard model final states, Gamma(W)(inv), of 0.213 GeV. Combining these results with those from the 1992-1993 data gives sigma(p (p) over bar-->W+X) x B(W-->e nu)/sigma(p (p) over bar-->Z+X) x B(Z-->ee) = 10.51+/-0.25, Gamma(W) = 2.152 +/- 0.066 GeV, and a 95% C.L. upper limit an Gamma(W)(inv) of 0.191 GeV. Using a sample with a luminosity of 505 nb(-1) taken at root s = 630 GeV, we measure sigma(p (p) over bar--> W+ X) x B(W --> e nu) = 658 +/- 67 pb. C1 NYU, New York, NY 10003 USA.

KOBAYASHI-MASKAWA MATRIX; SILICON VERTEX DETECTOR; TOP-QUARK PRODUCTION; B-MESON DECAYS; CP-VIOLATION; (P)OVER-BAR-P COLLISIONS; COLLIDER DETECTOR; ROOT-S=1.8 TEV; PHASES; PARAMETRIZATION AB This paper reports an updated measurement of the standard model CP violation parameter sin 2 beta using the CBF Detector at Fermilab. The entire run I data sample of 110 pb(-1) of proton-antiproton collisions at root s =1.8 TeV is used to identify a signal sample of similar to 400 B-->J/psi K-S(o) events, where J/psi --> mu(+)mu(-) and K-S(o) - pi(+) pi(-). The flavor of the neutral B meson is identified at the time of production by combining information from three tagging algorithms: a same-side tag, a jet-charge tag, and a soft-lepton tag. A maximum likelihood fitting method is used to determine sin 2 beta=0.79(-0.44)(+0.41)(stat + syst). This value of sin 2 beta is consistent with the standard model prediction, based upon existing measurements, of a large positive CP-violating asymmetry in this decay mode.

Sleptons produced at the CERN LHC through the cascade decays of squarks and gluinos can give a sizable number of events with 4 leptons. This channel could give a clean signature of supersymmetric lepton flavor violation under conditions which are identified. C1 Univ Oregon, Inst Theoret Sci, Eugene, OR 97403 USA.

Within the standard model, the K-L --> pi(o)nu<(nu)over bar> decay is dominated by direct CP violating processes, and thus an observation of the decay implies confirmation of direct CP violation. No events were observed, and we set an upper limit for the branching ratio of K-L --> pi(o)nu<(nu)over bar> to be < 5.9 x 10(-7) at the 90% confidence level.

Using a sample of 1.5x10(6) B meson pairs, we find the mean inclusive charged particle multiplicity to be 10.71+/-0.02(-0.15)(+0.21) for the decay of the pair. This corresponds to a mean multiplicity of 5.36+/-0.01(-0.08)(+0.11) for a single B meson. Using the same data sample, we have also extracted the mean multiplicities in semileptonic and nonleptonic decays. We measure a mean of 7.82+/-0.05(-0.19)(+0.21) charged particles per BE decay when both mesons decay semileptonically. When neither B mason decays semileptonically, we measure a mean charged particle multiplicity of 11.62+/-0.04(-0.18)(+0.24) per B (B) over bar pair. C1 Harvard Univ, Cambridge, MA 02138 USA.

Muonium and free mu(+) decay spectra are found to differ at O(alpha m(e) lm(mu)) from Doppler broadening and O(alpha(2)m(e)lm(mu)) from the Coulomb bound state potential. However, both types of corrections are shown to cancel in the total decay rate due to Lorentz and gauge invariance respectively, leaving a very small time dilation lifetime difference, (tau(M) - tau(mu+))/tau(mu+) = alpha(2)m(e)(2)/2m(mu)(2) similar or equal to 6 x 10(-10), as the dominant bound state effect. It is argued that other medium effects on the stopped mu(+) lifetime are similarly suppressed. C1 Brookhaven Natl Lab, Dept Phys, Upton, NY 11973 USA.

A partial wave analysis of the resonant structure of the tau-->3 pi pi(o)nu(tau) decay has been performed; the spectral decomposition of the four pion system is dominated by the omega pi and a(1)pi final states. The mass and width of the rho' resonance have been extracted from a fit to the tau-->omega pi nu(tau), spectral function. We have searched for second class currents in the decay tau-->omega pi nu(tau) using spin-parity analysis and established an upper limit on the non-rector current contribution.

We show that in a class of models including minimal supergravity, the up-type Higgs mass parameter has a focus point at the weak scale, where its value is highly insensitive to the universal scalar mass. As a result, scalar masses as large as 2 to 3 TeV are consistent with naturalness, and all squarks, sleptons and heavy Higgs scalars may be beyond the discovery reaches of the CERN Large Hadron Collider and proposed linear colliders. Gaugino and Higgsino masses are, however, still constrained to be near the weak scale. The focus point behavior is remarkably robust, holding for both moderate and large tan beta, any weak scale gaugino masses and A parameters, variations in the top quark mass within experimental bounds, and for large variations in the boundary condition scale.

In this way one can achieve a simultaneous understanding of low-lying mesons, baryons, and the nuclear force. The discussion is general and does not necessarily rely on the instanton-induced interaction. Any nonperturbative gluonic interaction between quarks, which is a sourer of the dynamical chiral symmetry breaking and explains the pi-p mass splitting, will imply an effective meson exchange picture in the baryons. Because of the (anti)screening there is a large difference between the initial 't Hooft interaction and the effective meson-exchange interaction. It is demonstrated that the effective meson-exchange interaction, adjusted to the baryon spectrum, does not bind the scalar diquark and does not induce any significant quark-diquark clustering in the nucleon because of the nontrivial role played by the Pauli principle.

Dimensions of sizes anywhere from similar to mm to similar to TeV-1 can be populated by bull; gravitons, vector bosons and fermions. In this paper the one-loop correction of these bulk particles to the muon magnetic moment ((MMM)) is investigated. In all the scenarios considered here it is found that the natural value for the MMM is O(10(-8)-10(-9)). One main result is that the contribution of each Kaluza-Klein graviton to the MMM is remarkably finite. The bulk graviton loop implies a Limit of similar to 400 GeV on the scale of strong gravity. This could be pushed up to similar to 1-2 TeV, even in the case of six extra dimensions, if the BNL E821 experiment reaches an expected sensitivity of similar to 10(-9). Limits on a bulk B-L gauge boson are interesting, but still allow for forces 10(6) - 10(7) times stronger than gravity at mm(-1) distances. The correction of a bulk right-handed neutrino to the MMM in one recent proposal for generating small Dirac neutrino masses is considered in the context of a two Higgs doublet model, and is found to be close to 10(-9). The contributions of all these bulk particles to the MMM are (roughly) independent of both the total number of extra dimensions and the dimension of the subspace occupied by the bulk states. Finally, limits on the size of "small" compact dimensions gotten from the MMM and atomic parity violation are determined and compared.

The condensates of interest correspond to scalar, vector, pseudoscalar, axial vector, and tensor Dirac structures. Working with correlators at zero chemical potential without factorization, we arrive at coupled equations for these four-quark condensates and the masses of certain light-quark mesons. We study the temperature dependence of the four-quark condensates and masses; in one of our models, factorization of the four-quark condensates is shown to be increasingly violated as the temperature is increased toward T-c. The 2(++) tensor mesons a(2)(1320)-f(2)(1270) are identified as especially sensitive probes of the four-quark condensates. C1 Univ Calif Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

We use factorized models for double distributions (DD's) (f) over bar(x,alpha) in which one factor coincides with the usual (forward) parton distribution and another specifies the profile characterizing the spread of the longitudinal momentum transfer. The model DD's are used to construct skewed parton distributions (SPD's). For small skewedness, the FV parts of SPD's H((x) over bar,xi) can be obtained by averaging forward parton densities f((x) over bar - xi alpha) with the weight p(alpha) coinciding with the profile function of the double distribution (f) over bar(x,alpha) at small x. We show that if the x(n) moments (f) over bar (n)(alpha) of DD's have the asymptotic (1 - alpha(2))(n + 1) profile, then the alpha profile of (f) over bar(x,alpha) far small x is completely determined by the small-x behavior of the usual parton distribution. We demonstrate that, for small xi, the model with asymptotic profiles for (f) over bar(a) is equivalent to that proposed recently by Shuvaev et al., in which the Gegenbauer moments of SPD's do not depend on xi. We perform a numerical investigation of the evolution patterns of SPD's and give an interpretation, of the results of these studies within the formalism of double distributions.

A sharp unimer-micelle transition is obtained due to the tuning of the solvating ability of sc-CO2 by profiling pressure, so that the block copolymer, in a semidilute solution, finds sc-CO2 a good solvent at high pressure and a poor solvent at low pressure. At high pressure the copolymer is in a monomeric state with a random coil structure. However, on lowering the pressure, aggregates are formed with a structure similar to aqueous micelles with the hydrocarbon segments forming the core and the fluorocarbon segments forming the corona of the micelle. This unimer-aggregate transition is driven by the gradual elimination of CO2 molecules solvating the hydrocarbon segments of the polymer. Comparison of these results with related data on the same polymer at different temperatures indicates that the transition is critically related to the density of the solvent. This suggests the definition of a critical micellization density, to our knowledge a new concept in colloid chemistry. C1 Univ Palermo, Dept Chem Phys, I-90128 Palermo, Italy.

This methodology, based on the application of a nonlinear iterative version of the Rayleigh-Ritz variational principle yields breather excitations in a very fast and efficient way in one or higher spatial dimensions. The typical convergence properties of the method are found to be super-linear, The usefulness of this technique is illustrated by studying the properties of the recently developed theoretical criteria for the excitation power thresholds for nonlinear modes.

The analyser allows the detection of only those x-rays transmitted by the subject that fall into the acceptance angle (central part of the rocking curve) of the monochromator/analyser system. As shown by Chapman et al, in addition to the x-ray attenuation, the method provides information on the out-of-plane angular deviation of x-rays. New images result in which the image contrast depends on the x-ray index of refraction and on the yield of small-angle scattering, respectively. We implemented DEI in the tomography mode at the National Synchrotron Light Source using 22 keV x-rays, and imaged a cylindrical acrylic phantom that included oil-filled, slanted channels. The resulting 'refraction CT image' shows the pure image of the out-of-plane gradient of the x-ray index of refraction. No image artefacts were present, indicating that the CT projection data were a consistent set. The 'refraction CT image' signal is linear with the gradient of the refractive index, and its value is equal to that expected. The method, at the energy used or higher, has the potential for use in clinical radiography and in industry. C1 Brookhaven Natl Lab, Dept Med, Upton, NY 11973 USA.

C. Luxon and L. G. Davis, Fusion Technology 8, Part 2A, 441 (1985)] are quantitatively consistent with recent computational modeling establishing that ExB(T) circulation is the main cause of changes in divertor plasmas with the direction of the toroidal magnetic field, B-T. Extensive two-dimensional measurements of plasma potential in the DIII-D tokamak divertor region are reported for the first time. The resulting ExB(T)/B-2 drift particle flux is calculated for standard (ion del B-T drift toward divertor X-point) and reversed B-T direction and for low (L) and high (H) confinement modes. Perpendicular field strengths of up to E similar to 5 kV/m are observed at the separatrix between the divertor private region and the scrape-off layer (SOL). The ExB(T) drift, which reverses with reversal of B-T, creates a poloidal circulation pattern in the divertor that convects 25%-40% of the total ion flow to the divertor target. The circulation strongly couples the various regions of the divertor and SOL and fuels the X-point region. An outward shift of the profiles is seen in reversed B-T.

For a wall at infinite distance from the plasma, the amount of external poloidal flux needed for stabilization is given by f = (kappa(2) - kappa)/(kappa(2) + 1), where kappa is the axisymmetric elongation and f is the ratio of vacuum rotational transform to the total transform.

The local Lyapunov exponents and the characteristic directions are functions of Lagrangian coordinates and time, which are completely determined once the flow field is specified. The characteristic directions that are associated with the spatial anisotropy of the problem, are prescribed in both Lagrangian and Eulerian frames. Coordinate transformation techniques are employed to relate the spatial distributions of the magnetic field, the induced current density, and the Lorentz force, which are usually followed in Eulerian frame, to those of the local Lyapunov exponents, which are naturally defined in Lagrangian coordinates.

The ballooning transform has been applied to the gyrokinetic equation, for the case of a large aspect ratio plasma with circular magnetic surfaces. A new eigenvalue code has been developed to solve the resulting integral equation, for the case of adiabatic electrons and full ion dynamics, thus taking into account both circulating and trapped ions. The goal has been to assess the validity of the ballooning transform for trapped ion modes. A scan over the parameter k(theta)rho(L) has been carried out to determine a lower threshold for applicability of the ballooning representation. Illustrative results of trapped ion modes (TIM) are presented, together with the comparison with the ones obtained using a global gyrokinetic code, for low toroidal wave numbers, and a local kinetic dispersion relation.

However, to optimize this process it is important to understand the biological mechanisms involved. Using a combination of techniques, including x-ray absorption spectroscopy, we have established the biochemical fate of arsenic taken up by Indian mustard (Brassica juncea). After arsenate uptake by the roots, possibly via the phosphate transport mechanism, a small fraction is exported to the shoot via the xylem as the oxyanions arsenate and arsenite. Once in the shoot, the arsenic is stored as an As-III-tris-thiolate complex. The majority of the arsenic remains in the roots as an As-III-tris-thiolate complex, which is indistinguishable from that found in the shoots and from As-III-tris-glutathione. The thiolate donors are thus probably either glutathione or phytochelatins. The addition of the dithiol arsenic chelator dimercaptosuccinate to the hydroponic culture medium caused a 5-fold-increased arsenic level in the leaves, although the total arsenic accumulation was only marginally increased. This suggests that the addition of dimercaptosuccinate to arsenic-contaminated soils may provide a way to promote arsenic bioaccumulation in plant shoots, a process that will be essential for the development of an efficient phytoremediation strategy for this element.

However, the physiological basis of this tolerance mechanism is unknown. We have investigated the role of vacuolar compartmentalization and chelation in this Ni tolerance. A direct comparison of Ni contents of vacuoles from leaves of T. goesingense and from the non-tolerant non-accumulator Thlaspi arvense L. showed that the hyperaccumulator accumulates approximately 2-fold more Ni in the vacuole than the non-accumulator under Ni exposure conditions that were non-toxic to both species. Using x-ray absorption spectroscopy we have been able to determine the likely identity of the compounds involved in chelating Ni within the leaf tissues of the hyperaccumulator and non-accumulator. This revealed that the majority of leaf Ni in the hyperaccumulator was associated with the cell wall, with the remaining Ni being associated with citrate and His, which we interpret as being localized primarily in the vacuolar and cytoplasm, respectively. This distribution of Ni was remarkably similar to that obtained by cell fractionation, supporting the hypothesis that in the hyperaccumulator, intracellular Ni is predominantly localized in the vacuole as a Ni-organic acid complex.

The enzyme is an 80.6-kDa inner membrane protein that functions in vivo as a 2-acylglycerophosphoethanolamine acyltransferase. The E. coli aas open reading frame was inserted into the expression plasmid pET28a so that, upon expression, a 21-amino-acid extension containing 6 consecutive histidine residues was added to the carboxyl terminus. The plasmid was designated pAasH. The activity of Aas in membranes was assessed from several cell lines. Membranes from the commonly used host line BL21(DE3) containing pAasH accumulated 30-fold and 38-fold more Aas activity than membranes from BL21(DE3) cells lacking the plasmid, when induced with isopropyl beta-D-thiogalactopyranoside (IPTG) or lactose, respectively. When pAasH was expressed under IPTG induction in cell line C41(DE3), a previously described cell line selected to enhance the expression of membrane proteins, Aas levels accumulated to 135-fold higher levels than in the cell line lacking the plasmid. Functional Aas can be isolated from either BL21(DE3) or C41(DE3) cell lines by differential centrifugation, followed by detergent extraction with Triton X-100 and nickel nitrilotriacetic acid affinity chromatography. The overexpression of Aas in cell line C41(DE3) is noteworthy compared to cell line BL21(DE3) because it results in a 3- to 4-fold higher accumulation of active enzyme in the membrane fraction and a lower proportion of inactive protein in the inclusion body.

By using an aperture mask located close to the f/25 secondary, the 10 m Keek primary mirror was transformed into a separate-element, multiple-aperture interferometer. This has allowed diffraction-limited imaging of a large number of bright astrophysical targets, including the geometrically complex dust envelopes around a number of evolved stars. The successful restoration of these images, with dynamic ranges in excess of 200:1, highlights the significant capabilities of sparse aperture imaging as compared with more conventional filled-pupil speckle imaging for the class of bright targets considered here. In particular, the enhancement of the signal-to-noise ratio of the Fourier data, precipitated by the reduction in atmospheric noise, allows high-fidelity imaging of complex sources with small numbers of short-exposure images relative to speckle.

The instrument consists of a helium neon (HeNe) laser for excitation, an acousto-optic tunable filter (AOTF) for wavelength discrimination, and an avalanche photodiode for detection. The AOTF is the primary component of this system and has been selected based on its spectral range (600-900 nm) along with its high resolution, similar to 7.5 cm(-1). Labview(TM) based software for controlling the AOTF frequency and the signal acquisition has also been developed. Several different samples were analyzed (both solids and liquids) using this instrument for the evaluation of parameters such as spectral resolution, sensitivity, and data acquisition speed for certain environmentally important compounds. The results from these measurements are compared with those using a conventional laboratory Raman system consisting of a grating-based spectrograph and a charge-coupled device.

We use the Ag 3d(5/2) and 3d(3/2) core levels and their associated core valence-valence Auger decays, the Ag M5VV and M4VV Auger lines, to demonstrate this technique. Ag M5VV and M4VV Auger spectra were obtained in coincidence with 3d(5/2) and 3d(3/2) core photoelectrons, respectively. We have also measured the 3d(5/2) and 3d(3/2) core level spectra in coincidence with M5VV and M4VV Auger electrons. In the coincidence spectra, the contribution from the spin-orbit partner is considerably reduced but, in general, not eliminated. However, by measuring all four coincidence spectra, enough information is obtained to unambiguously assess and remove the unwanted contributions and thus determine the intrinsic line shape of the M5VV and M4VV Auger lines. As a cross-check of this subtraction technique, we find that the intrinsic M5VV and M4VV line shapes give an excellent account of the conventional, noncoincidence Ag M4,5VV spectrum with the expected 6:4 ratio. The correction technique described here can be applied to a large number of systems where the close separation of core lines produces additional spectral features in the coincidence measurements of their associated Auger spectra.

Part II of the series describes the use of identical fibers and additional multimode fibers, both with and without Bragg gratings, to perform near infrared spectroscopy. The demodulation system being developed at NASA Langley Research Center currently requires the use of a single mode optical fiber. Attempts to use this single mode fiber for spectroscopic analysis are problematic given its small core diameter, resulting in low signal intensity. Nonetheless, we have conducted a preliminary investigation using a single mode fiber in conjunction with an infrared spectrometer to obtain spectra of a high-performance epoxy resin system. Spectra were obtained using single mode fibers that contained Bragg gratings; however, the peaks of interest were barely discernible above the noise. The goal of this research is to provide a multipurpose sensor in a single optical fiber capable of measuring a variety of chemical and physical properties.

We present results from simultaneous measurements taken by TRACE in chromospheric and transition region (C iv) images, high-resolution magnetograms taken by MDI, and spectra of chromospheric (C ii) and transition region lines (O vi) obtained with the SUMER instrument on SOHO. Enhanced emission in the C iv line is generally co-spatial with the magnetic pattern in the photosphere. We propose a mechanism of electro-mechanical coupling between the photosphere and upper layers of atmosphere based on hydrodynamic cumulation of energy produced by reconnecting flux tubes in the photosphere/chromosphere region (Tarbell et al., 1999). We believe that a basic process causing energetic events is the cascade of shock waves produced by colliding and reconnecting flux tubes. The continuous supply of flux tubes in the 'magnetic carpet' ensures the ubiquitous nature of this process and its imprint on the upper atmosphere. The appearance of bright transients often, but not always, correlates with canceling mixed polarity magnetic elements in the photosphere. In other cases, transients occur in regions of unipolar flux tubes, suggesting reconnection of oblique components. Transients are also seen in regions with no fields detected with the MDI sensitivity; these may be reconnections of tiny features with diameters less than 100 km. Blinkers and other bright transients are often accompanied by two directional plasma jets. These may be generated by cylindrical self-focusing of shock fronts or by collision of shocks produced by neighboring reconnection processes. The observations suggest that stronger emissions correspond to lower velocity jets, and vice versa; this property is a natural consequence of the proposed mechanism. Plasma flows are always seen whenever the slit crosses strong magnetic flux tubes or vertices of converging flows in the supergranular network. The overall energy distribution between heating and plasma flows is an intrinsic feature of our mechanism. C1 Lockheed Martin Solar & Astrophys Lab, Palo Alto, CA 94304 USA.

Substitution of a larger B' ion in solid solution for B can progressively drive the system to complete disorder as in Y(2)(Zr(y) Ti(1-y))(2)O(7), producing an oxygen-ion conductivity, sigma greater than 10(-2) S/cm at 1000 degrees C. comparable to the values of 10(-1) S/cm found for M(3+)-stabilized cubic zirconias. Rietveld analyses of neutron and X-ray powder diffraction data have been employed to obtain structural data for the related systems Y(2)(Sn(y)Ti(1-y))(2)O(7), Y(2)(Zr(y)Sn(1-y))(2)O(7), Gd(2)(Sn(y)Ti(1-y))(2)O(7) and (Sc(z)Yb(1-z))(2)Ti(2)O(7) to test whether the state of disorder and attendant ionic conductivity are indeed determined by R(A)/(R(B),R(B)) This was not the case for the Sn-Ti solid solutions: they retained an ordered pyrochlore structure for all values of y, The slight variation of ionic conductivity (less than one order of magnitude with a maximum in sigma at intermediate y) was successfully explained by the structural data. The behavior of Y(2)(Zr(y)Sn(1-y))(2)O(7) solid solutions was very similar to that of the Zr-Ti phases. Neutron powder diffraction profiles were recorded as fully-ordered Y(2)Sn(2)O(7) and highly-disordered Y(2)(Zr(0.6)Ti(0.4))(2)O(7) were heated in situ at temperatures in the range 20-1500 degrees C. The structure of Y(2)Sn(2)O(7) steadfastly remained fully-ordered over this temperature range. The principal change in the structure was increase in the positional coordinate, x, for O(1), corresponding to increased distortion of the oxygen-ion array as temperature was increased, a consequence of greater thermal expansion of the A(3-)-O bond relative to change in the B(4+)-O separation. The highly-disordered cation arrangements in Y(2)(Zr(0.6)Ti(0.4))(2)O(7) remain unchanged up to 1250 degrees C when the oxygen array began to undergo further disorder. The same anion site occupancies were observed during heating and cooling cycles suggesting that their distribution does represent an equilibrium state.

Oxidation kinetic studies with the un-oxidized alloys show a nearly parabolic dependence on time of oxide-scale growth rate, but a significantly increased growth rate with a coating of LSCo (La0.6Sr0.4CoO3-delta) compared to those without and with the coatings of LSM (La0.85Sr0.15MnO3) + LSGM (La0.8Sr0.2Ga0.83Mg0.17O2.815) and platinum. Short-term resistance measurements in stagnant air as a function of temperature with pre-oxidized alloys indicate that the oxide scale has a semiconducting transport property. The overall activation energy includes a term from small-polaron hopping inside the oxide scale Delta H-m and terms Delta H-i and Delta H-j from charge transfers at the electrode/oxide-scale and alloy/oxide-scale interfaces, respectively. For the LSCo electrode, long-term resistance measurements as a function of time with un-oxidized alloys reveal a secondary oxidation mechanism related to the formation of an insulating spinel phase in addition to a primary oxidation mechanism associated with the formation of Cr2O3. SEM observations show that oxidation of the un-oxidized alloy in the presence of an oxide electrode results in considerable interdiffusion of Cr and the electrode cations, especially Co, across the interfaces. Since the ASR values of the oxide scale measured with oxide electrodes quickly approach the permitted limit of a practical SOFC, highly recommended for prevention of a secondary electrochemical oxidation of iron-based alloy interconnects is (1) the use of an oxide coating having purely electronic conductivity and/or (2) prior-to-use conditioning of the alloys via pre-oxidation.

This conclusion results from comparing symmetries of experimental surface LEED patterns with bulk X-ray diffraction data which are converted to the conditions of the LEED experiment. This conclusion is also based upon an analysis of relative diffraction spot spacings in LEED. Hence, none of the three surfaces exhibits a massive lateral reconstruction, i.e. massive deviation from quasicrystallinity. The LEED pattern of the fivefold surface is distinct from the LEED pattern of the pseudo-tenfold surface of an orthorhombic approximant. We believe that this rules out the possibility that the fivefold surface of the icosahedral quasicrystal reconstructs to an approximant with tenfold or pseudo-10-fold symmetry. The twofold and threefold surfaces facet more readily, indicating qualitatively that they are less stable than the fivefold surface. (C) 2000 Elsevier Science B.V. All rights reserved.

The formation of three-dimensional islands at all the coverages reflects the relatively high mobility of Cu atoms on TiO2 at room temperature (diffusion constant greater than or equal to 4 x 10(-10) cm(2)/s) and the weak interaction between Cu and TiO2 compared with Cu-Cu bonding. At low coverages (< 0.5 ML)I the Cu islands exhibit self-limiting growth: with increasing coverage, the average island size remains almost constant, and the island density increases. At higher coverages (>0.5 ML), the average island size scales with coverage, but this increase in island size is primarily due to an increase in height, not diameter. Although larger islands can be formed by annealing, the average size of the islands is nearly independent of coverage for any given annealing temperature. We propose two general schemes that can simultaneously explain the increase in island density with increasing coverage and the narrow island size distribution. In the first scheme, the rate at which adatoms attach to existing islands drops rapidly as the island size increases. This could be due to the existence of strain fields that accommodate the lattice mismatch at the interface between the Cu islands and the TiO2 substrate. Adatoms rejected by the islands are then available for nucleation of new islands. In the second scheme, the rate at which adatoms reach existing islands drops rapidly as the Cu coverage increases. This could be related to continued nucleation of islands at defects in the TiO2 surface. (C) 2000 Elsevier Science B.V. All rights reserved. C1 Sandia Natl Labs, Livermore, CA 94550 USA.

These analyses were complemented by experiments intended to estimate the water-soluble fraction of the submicron carbonaceous material. Our results can be summarized as follows. Depending on the sample, between 35% and 80% of total aerosol carbon is associated with the submicron fraction. Total submicron carbon was well correlated with black carbon, a unique tracer for incomplete combustion. These correlations and the approximately constant total to black carbon ratios, suggest that the majority of submicron total carbon is of primary combustion derived origin. No systematic relationship between total submicron aerosol carbon and sulfate concentrations was found. Sulfate concentrations were, with a few exceptions, significantly higher than total carbon. Our experiments have demonstrated that water exposure removed between 36% and 72% of total carbon from the front filter, suggesting that a substantial fraction of the total submicron aerosol organic carbon is water-soluble. An unexpected result of this study is that water exposure of filter samples caused substantial removal of, nominally insoluble, submicron black carbon. Possible reasons for this observation are discussed. C1 Univ Calif Berkeley, Lawrence Berkeley Lab, Environm Energy Technol Div, Berkeley, CA 94720 USA.

ACE-2 studied the outflow of European aerosol into the NE Atlantic atmosphere. A variety of air masses were sampled during ACE-2 including Atlantic, polar, Iberian Peninsula, Mediterranean, and Western European. Reported here are mass size distributions of non-sea salt (nss) sulfate, sea salt, and methanesulfonate and submicron and supermicron concentrations of black and organic carbon. Optical parameters include submicron and supermicron aerosol scattering and backscattering coefficients at 550 nm, the absorption coefficient at 550 +/- 20 nm, the Angstrom exponent for the 550 and 700 nm wavelength pair, and single scattering albedo at 550 nm. All data are reported at the measurement relative humidity of 55%. Measured concentrations of nss sulfate aerosol indicate that, relative to ACE-1, ACE-2 aerosol during both marine and continental flow was impacted by continental sources. Thus, while sea salt controlled the aerosol chemical composition and optical properties of both the submicron and supermicron aerosol during ACE-1, it played a relatively smaller role in ACE-2. This is confirmed by the larger average Angstrom exponent for ACE-2 continental aerosol of 1.2 +/- 0.26 compared to the ACE-1 average of -0.03 +/- 0.38. The depletion of chloride from sea salt aerosol in ACE-2 continental air masses averaged 55 +/- 25% over all particle sizes. This compares to the ACE-2 marine average of 4.8 +/- 18% and indicates the enhanced interaction of anthropogenic acids with sea salt as continental air masses are transported into the marine atmosphere. Single scattering albedos averaged 0.95 +/- 0.03 for ACE-2 continental air masses. Averages for ACE-2 and ACE-1 marine air masses were 0.98 +/- 0.01 and 0.99 +/- 0.01, respectively.

Mathematical modeling of pyrite oxidation in variably saturated reactive flow systems is challenging because (1) it occurs through a complex interplay of multi-phase flow and transport processes, and (2) aqueous concentrations of key species vary over tens orders of magnitude in different redox conditions. Here, we present a general multi-phase reactive transport model for redox processes. Two alternative implementations were made in the TOUGHREACT and TOUGH2-CHEM simulation codes which use sequential iteration and simultaneous solution, respectively. Both codes are used to simulate a fully and a variably saturated pyrite oxidation problem with simple 1-D flow and reaction conditions. Results from both codes indicate that the effects of oxygen partial pressure reduction due to reactions on the fluid flow is not significant under ambient conditions. However, it must be noted that when fluid flow and chemical reactions are strongly coupled, such as when boiling takes place in geothermal reservoirs, this could be essential. The fully simultaneous approach has a complete process description. The sequential iteration approach is found to be more efficient computationally. The oxygen gas diffusion process plays a dominant role in the chemical evolution for pyrite oxidation in unsaturated conditions. An example in 2-D fractured rock is presented to demonstrate pyrite oxidation under complex flow and geochemical conditions. This example shows that pyrite oxidation exerts strong influence on hydrogeochemical evolution in variably saturated flow systems. The alteration of primary rock minerals and the development of secondary mineral assemblages predicted are consistent with field observations. This example serves as a prototype for oxidative weathering processes with broad significance for geoscientific, engineering, and environmental applications.

I measured midday A(net) in the upper canopy of maturing loblolly pine (Pinus taeda L.) trees in the piedmont region of the southeastern USA on 146 sunny days over 36 months. Concurrent data for leaf conductance and photosynthetic CO2 response curves (A(net)-C-i curves) were used to estimate the relative importance of stomatal limitations to CO2 assimilation in the field. In fully expanded current-year and I-year-old needles, midday light-saturated A(net) was constant over much of the growing season (5-6 mu mol CO2 m(-2) s(-1)), except during drought periods. During the winter season (November-March), midday A(net) of overwintering needles varied in proportion to leaf temperature. Net CO2 assimilation at light saturation occurred when daytime air temperatures exceeded 5-6 degrees C, as happened on more than 90% of the sunny winter days. In both age classes of foliage, winter carbon assimilation accounted for approximately 15% of the daily carbon assimilation on sunny days throughout the year, and was relatively insensitive to year-to-year differences in temperature during this season. However, strong stomatal limitations to A(net) occurred as a result of water stress associated with freezing cycles in winter. During the growing season, drought-induced water stress produced the largest year-to-year differences in seasonal CO2, assimilation on sunny days. Seasonal A(net) was more drought sensitive in current-year needles than in 1-year-old needles. Relative stomatal limitations to daily integrated A(net) were approximately 40% over the growing season, and summer drought rather than high temperatures had the largest impact on summer A(net) and integrated annual CO2 uptake in the upper crown. Despite significant stomatal limitations, a long duration of near-peak A(net) in the upper crown, particularly in I-year-old needles, conferred high seasonal and annual carbon gain.

Few studies, however, have considered whether radial variation in sap velocity and the proportion of sapwood active in water transport are significant sources of uncertainty in the extrapolation process. Therefore, radial profiles of sap velocity were examined as a function of stem diameter and sapwood thickness for yellow-poplar (Liriodendron tulipifera L.) trees growing on two adjacent watersheds in eastern Tennessee. The compensation heat pulse velocity technique was used to quantify sap velocity at four equal-area depths in 20 trees that ranged in stem diameter from 15 to 69 cm, and in sapwood thickness from 2.1 to 14.8 cm. Sap velocity was highly dependent on the depth of probe insertion into the sapwood. Rates of sap velocity were greatest for probes located in the two outer sapwood annuli(P1 and P2) and lowest for probes in closest proximity to the heartwood (P3 and P4). Relative sap velocities averaged 0.98 at P1, 0.66 at P2, 0.41 at P3 and 0.35 at P4. Tree-specific sap velocities measured at each of the four probe positions, divided by the maximum sap velocity measured (usually at Fl or P2), indicated that the fraction of sapwood functional in water transport (f(S)) varied between 0.49 and 0.96. There was no relationship between f(S) and sapwood thickness, or between f(S) and stem diameter. The fraction of functional sapwood averaged 0.66 +/- 0.13 for trees on which radial profiles were determined. No significant depth-related differences were observed for sapwood density, which averaged 469 kg m(-3) across all four probe positions. There was, however, a significant decline in sapwood water content between the two outer probe positions (1.04 versus 0.89 kg kg(-1)). This difference was not sufficient to account for the observed radial variation in sap velocity. A Monte-Carlo analysis indicated that the standard error in estimated mean f(S) declined rapidly with increasing sample size. At n = 10, the coefficient of variation in mean f(S) was 7% and at n = 15 it was slightly less than 5%. These observations indicate that radial variation in sap velocity is an important, albeit often overlooked, source of uncertainty in the scaling process. Failure to recognize that not all sapwood is functional in water transport will introduce systematic bias into estimates of both tree and stand water use. Future studies should devise sampling strategies for assessing radial variation in sap velocity and such strategies should be used to identify the magnitude of this variation in a range of non-, diffuse- and ring-porous trees.

The spatial variabilities in both the fracture and matrix continua motivate us to treat some of the fracture and matrix medium properties as stochastic processes. Hence flow through heterogeneous, fractured porous media is also amenable to stochastic analysis. In particular, we develop a moment equation-based stochastic theory for flow in fractured porous media. We derive general equations governing the statistical moments of the pressure heads in such media by perturbation expansions. The solutions of these moment equations are the first two moments of the pressure heads. These may be used to construct the confidence intervals of the fracture and matrix pressure heads, which are measures of uncertainties caused by incomplete knowledge of the fracture and matrix medium heterogeneities. The resulting moment equations of pressure heads are coupled and need to be solved sequentially in an iterative manner. The two-dimensional version of the equations is implemented numerically and illustrated with some examples. C1 Univ Calif Los Alamos Natl Lab, Geoanal Grp EES5, Los Alamos, NM 87545 USA.

Experiments were performed using a jet turbine engine lubricant in the as-received condition or with particulate contaminants added. The added particulate contaminants were Arizona test dust or glycothermally synthesized alpha-Al2O3. Wear performance of the all-steel and hybrid rolling systems was evaluated with and without particulate contaminants in the lubricant. Wear surfaces were analyzed using optical microscopy, scanning electron microscopy, surface profilometry, and atomic force microscopy. Wear mechanisms, volume specific wear rates and modes of failure were determined for all systems. The primary wear mechanism produced in rolling contact fatigue experiments is shown to be contact stress fatigue, with secondary mechanisms of indenting, cutting, plowing and embedding occurring as particulate debris passes through the elastohydrodynamic lubricant layer between the ball and rod surfaces.

A transient, three-dimensional, turbulent heat transfer and fluid flow model was developed to calculate the temperature and velocity fields, thermal cycles, and the shape and size of the fusion zone. The kinetics of the alpha-->beta allotropic transformation during continuous heating and the corresponding (alpha+beta)/beta phase boundary were calculated using a modified Johnson-Mehl-Avrami (JMA) equation and the calculated thermal cycles. The modeling results were compared with the real-time phase mapping data obtained using a unique spatially resolved X-ray diffraction technique with synchrotron radiation. The real-time evolution of grain structure within the entire weld heat-affected zone (HAZ) was modeled in three dimensions using a Monte Carlo technique. The following are the major findings. First, the rates of heat transfer and fluid flow in the titanium weld pool during gas tungsten are welding (GTAW) are significantly enhanced by turbulence, and previous calculations of laminar fluid flow and heat transfer in are-melted pools need to be re-examined. The fusion zone geometry, and the alpha/(alpha+beta) and (alpha+beta)/beta phase boundaries in the HAZ could be satisfactorily predicted. Second, comparison of real-lime alpha-->beta transformation kinetics with the rates computed assuming various alternative reaction mechanisms indicates the transition was most likely controlled by the transport of Ti atoms across the alp interface. Third, comparison of the experimental data with the simulated results indicates the real-rime evolution of the grain structure around the weld pool could be simulated by the Monte Carlo technique. Finally, the in sight developed in this research could not have been achieved without concomitant modeling and experiments. C1 Penn State Univ, Dept Mat Sci & Engn, University Pk, PA 16802 USA.

Stabilization is thought to involve disruption of the interaction between the p53 protein and Mdm2, which targets p53 for degradation. Here we show that the direct association between a p53 N-terminal peptide and Mdm2 is disrupted by phosphorylation of the peptide on Thr's but not by phosphorylation at other N-terminal sites, including Ser(15) and Ser(37). Thr(18) was phosphorylated in vitro by casein kinase (CK1); this process required the prior phosphorylation of Ser's Thr's was phosphorylated in vivo in response to DNA damage, and such phosphorylation required Ser's. Our results suggest that stabilization of p53 after ionizing radiation may result, in part, from an inhibition of Mdm(2) binding through a phosphorylation-phosphorylation cascade involving DNA damage-activated phosphorylation of p53 Ser(15) followed by phosphorylation of Thr(18).

The model can simulate several simultaneously occurring attenuation processes including aerobic and anaerobic biological degradation processes. The developed model was applied to analyze field-scale transport and biodegradation processes occurring at the Area-6 site in Dover Air Force Base, Delaware. The model was calibrated to field data collected at this site. The calibrated model reproduced the general groundwater flow patterns, and also, it successfully recreated the observed distribution of tetrachloroethene (PCE), trichloroethene (TCE), dichloroethylene (DCE), vinyl chloride (VC) and chloride plumes. Field-scale decay rates of these contaminant plumes were also estimated. The decay rates are within the range of values that were previously estimated based on lab-scale microcosm and field-scale transect analyses. Model simulation results indicated that the anaerobic degradation rate of TCE, source loading rate, and groundwater transport rate are the important model parameters. Sensitivity analysis of the model indicated that the shape and extent of the predicted TCE plume is most sensitive to transmissivity values. The total mass of the predicted TCE plume is most sensitive to TCE anaerobic degradation rates. The numerical model developed in this study is a useful engineering tool for integrating field-scale natural attenuation data within a rational modeling framework. The model results can be used for quantifying the relative importance of various simultaneously occurring natural attenuation processes. Published by Elsevier Science B.V.

Flow and transport are considered in the vertical cross-section. The Dupuit approximation and conformal mapping onto the complex potential domain are employed to determine the velocity and concentration distributions, respectively. We use this solution to derive a priori conditions under which widely used I-D analytical solutions with constant velocity and dispersion coefficients provide accurate approximations. These conditions are formulated in terms of aquifer parameters, such as hydraulic conductivity, porosity and dispersivities, and remediation strategy, e.g., well spacing and pumping regimes.

Experiments were performed on four, centimeter-scale slabs of Culebra dolomite taken from the Waste Isolation Pilot Plant (WIPP) site. These tests involved the diffusion of potassium iodide into a single edge of each brine-saturated rock slab, while X-ray absorption imaging was used to measure the two-dimensional relative concentration distribution at different times during the experiment. X-ray imaging was also used to measure the heterogeneous, two-dimensional porosity distribution of each rock slab. The resulting high-resolution data provide unique insight into the spatially varying diffusion characteristics of each heterogeneous rock sample, which traditional methods such as through-diffusion experiments cannot. In these tests, significant variations in the diffusion coefficient were calculated over the relatively small length (centimeter) and time scales (months) investigated. Results also indicated that these variations were related to the heterogeneous porosity characteristics of each rock sample. Not only were the diffusion coefficients found to depend on the magnitude of the porosity but also on its spatial distribution. Specifically, the geometry, position, and orientation of the heterogeneous porosity features populating each rock slab appeared to influence the diffusion characteristics.

Phosphorylation of a conserved aspartyl residue induces structural changes that convert the protein from an inactive to an active state. The short half-life of the aspartyl-phosphate has precluded detailed structural analysis of the active protein. Persistent activation of Escherichia coli CheY was achieved by complexation with beryllofluoride (BeF3-) and the structure determined by NMR spectroscopy to a backbone r.m.s.d. of 0.58(+/-0.08) Angstrom. Formation of a hydrogen bond between the Thr87 OH group and an active site acceptor, presumably Asp57.BeF3-, stabilizes a coupled rearrangement of highly conserved residues, Thr87 and Tyr106, along with displacement of beta 4 and H4, to yield the active state. The coupled rearrangement may be a more general mechanism for activation of receiver domains. (C) 2000 Academic Press.

Subsequently the reverse alpha' --> gamma transformation was instigated by heating the coupons to 680 degrees C. The retransformation was monitored, in situ, by dilatometry and neutron Bragg edge diffraction (BED). Results from the two techniques show good agreement and suggest that the transformation kinetics are best described by two Avrami exponents, n = 2.5 and n = 0.2 respectively. A limited discussion of the lattice parameter evolution during the transformation is included. Possible mechanisms for growth dynamics and stress relaxation are discussed.

It was found that the plateau stress of the SG91A foam exhibited strain rate dependence, in a manner similar to other metallic foams such as AZ91 foam and ALPORAS. In the present study, efforts were made to correlate the plateau stress with the density of different foams, and it was further compared with existing models. II is of interest to note that the absorption energy normalized by the relative density at the dynamic strain rate is similar to 60% higher than that at quasi-static strain rates (similar to 1 x 10(-3) s(-1)).

These studies reveal that RNA polymerase molecules possess different intrinsic transcription rates and different propensities to pause and stop. The data also show that reversible pausing is a kinetic intermediate between normal elongation and the arrested state. The conformational metastability of RNA polymerase revealed by this single-molecule study of transcription has direct implications for the mechanisms of gene regulation in both bacteria and eukaryotes.

These ICP characteristics were investigated by measurements of the ionic to atomic spectral line intensity ratio of a test element (e.g. Mg and Zn). The effect of matrices of calcium (CaCO(3) and CaF(2)), strontium (SrCO(3)), lithium (Li(2)O, Li(2)CO(3) and LiF), magnesium (pure Mg and MgO), and aluminium metal on plasma conditions was studied using laser ablation sampling. Two Nd:YAG lasers were used to ablate the test element and the matrix simultaneously. Different amounts of matrix were ablated by varying one laser irradiance; the laser irradiance fur the ablation of the test element was kept constant. Strontium, calcium, and magnesium had a more pronounced matrix effect than the easily ionizable elements (Li, Na and K). The matrix effect was independent of the anion. Experimental results suggest that the matrix effects may be due to a mechanism that involves the second ionization level of the elements (Sr, Ca and Mg). Published by Elsevier Science B.V.

The elements use the linear interpolation functions of the original mesh, but each element is associated with a single node. As a result, a favourable constraint ratio for the volumetric response is obtained for problems in solid mechanics. The uniform strain elements do not require the introduction of additional degrees of freedom and their performance is shown to be significantly better than that of three-node triangular or four-node tetrahedral elements. In addition, nodes inside the boundary of the mesh are observed to exhibit superconvergent behaviour for a set of example problems. Published in 2000 by John Wiley & Sons, Ltd.

These states are determined to decay by spin-orbit autodetachment. In contrast, the P-2(3/2) CTTS state has a lifetime greater than 225 ps for even the smallest cluster studied, n = 6.

In Kr the relative W value increases slightly at the K-edge, which is at 14.3 keV. In liquid TMG the observed ion yield drops at the Ge K-edge (11.1 keV) and shows two minima separated by 10 eV. This ion-yield spectrum is a mirror image of the absorption spectrum, as represented by the gas-phase ion-yield spectrum. The observation of such an inverted spectrum in liquids is shown to be due in large part to inefficiency of collection of charges. This is a consequence of the large Ge cross sections above the edge which concentrates the region of irradiation near the entrance window, increasing the local dose rate and enhancing recombination. The yield of excited states in mixtures of TMG and toluene drops at the Ge K-edge by the amount expected considering the large X-ray fluorescence yield.

Three principal compounds have core masses of ca. 4.3, 5.6, and 8.2 kDa tin the range of similar to 20-40 Au atoms), and show structured optical absorption spectra with clear optical absorption onsets near 1.7, 1.3, and 1.0 eV, respectively. Each of these shows unusually strong chiroptical activity in the metal-based electronic transitions across the near-infrared, visible, and near-ultraviolet regions, whereas neither the crude (unseparated) mixture nor its higher molecular weight components possess such strong optical activity. The location and strength of the optical activity suggest a metal electronic structure that is highly sensitive to the chiral environment imposed by the glutathione adsorbate groups, if indeed the gold core is not inherently chiral. Mechanisms that could account for the observed optical activity are discussed, but the mere presence of strong chiroptical effects in this metallic-cluster system places these novel compounds in a special class of molecular substances. Previously known giant metal-cluster compounds land nanocrystals) have not been reported to exhibit significant optical activity. With these results, there emerges a rather complete picture of the evolution of optical and electronic properties of thiol-based gold cluster compounds (or self-assembled monolayer passivated gold nanocrystals) from 20 to 1000 Au atoms (0.7-3.2 MI core diameter).

Intramolecular hydrogen exchange in the octahedral iridium(III) dihydrogen dihydride complexes IrXH(2)(eta(2)-H(2))(PR(3))(2) (X = Cl, Br, I) SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID INELASTIC NEUTRON-SCATTERING; POTENTIAL BASIS-SETS; MOLECULAR-HYDROGEN; HYDRIDE LIGANDS; POLARIZATION FUNCTIONS; SOLUTION EQUILIBRIUM; PERTURBATION-THEORY; COUPLED-CLUSTER; HARTREE-FOCK; SOLID-STATE AB Density functional calculations (B3LYP) on IrXH(2)(eta(2)-H(2))(PR(3))(2) for X = Cl, Br, I and R = H, Me and inelastic neutron scattering studies for X = Cl, Br, I and R = Pr(i) are used to elucidate the mechanisms for the intramolecular dihydrogen/hydride exchange. The two lowest energy processes are rotation of the dihydrogen ligand and oxidative addition of the dihydrogen to form an intermediate Ir(V) tetrahydride, which undergoes rapid reductive elimination to interchange the dihydrides and the dihydrogen. The use of PMe(3) as a model phosphine is essential to bring the calculated barriers for the dihydrogen/hydride interchange into agreement with the experimental observations. The activation energy for site exchange (1.9 kcal/mol) is found to be in excellent agreement with the experimental result obtained for X = Cl (1.5(2) kcal/mol), and the calculations show a slight decrease in this value from X = C1 to I. Comparison between calculated rotational barriers (0.3 to 0.7 kcal/mol) and experimental values obtained for IrXH(2)(eta(2)-H(2))(PR(3))(2) (X = Cl, Br, I; R = Pr(i)) (0.5 to 1.0 kcal/mol) also demonstrates that the quantitative estimate of the barrier to rotation requires PMe(3) as the minimal model ligand.

Inhibition was competitive with respect to C-10-PQH(2) but noncompetitive with respect to horse heart cyt c or plastocyanin (PC). Inhibition was also pH-sensitive, with an apparent pK at about 7, above which inhibition was stronger, suggesting that binding occurred at or near a protonatable amino acid residue. Equilibrium binding titrations revealed ca. 1.4 tight Cu2+ binding sites with a K-D of about 0.5 mu M and multiple (>8) weak (K-D > 50 mu M) binding sites per complex. Pulsed electron paramagnetic resonance (EPR) techniques were used to identify probable binding sites for inhibitory Cu2+. A distinct enhancement of the relaxation time constant for the EPR signal from bound Cu2+ was observed when the cyt f was paramagnetic, The magnitude and temperature-dependence of this relaxation enhancement were consistent with a dipole interaction between Cu2+ and the cyt f (Fe3+) heme at a distance of between 30 and 54 Angstrom, depending upon the relative orientations of Cu2+ and cyt f heme g-tensors, Two-pulse electron spin-echo envelope modulation (ESEEM) and 4-pulse 2-dimensional hyperfine sublevel correlation (2D HYSCORE) measurements of Cu2+ bound to isolated cyt b(6)f complex indicated the presence of a weakly coupled nitrogen nucleus. The nuclear quadrupole interaction (NQI) and the hyperfine interaction (HFI) parameters identified one Cu2+ ligand as an imidazole nitrogen of a His residue, and electron-nuclear double resonance (ENDOR) confirmed the presence of a directly coordinated nitrogen, A model of the 3-dimensional structure of the cytochrome b(6)f complex was constructed on the basis of sequences and structural similarities with the mitochondrial cyt bc(1) complex, for which X-ray structures have been solved. This model indicated three possible His residues as ligands to inhibitory Cu2+. TWO Of these are located on the "Rieske" iron-sulfur protein protein (ISP) while the third is found on the cyt f protein. None of these potential ligands appear to interact directly with the quinol oxidase (Q(o)) binding pocket. A model is thus proposed wherein Cu2+ interferes with the interaction of the ISP protein with the Q(o) site, preventing the binding and subsequent oxidation of plastoquinonol. Implications for the involvement of ISP "domain movement" in Q(o) site catalysis are discussed. C1 Washington State Univ, Inst Biol Chem, Pullman, WA 99164 USA.

These heterogeneous peptides adopt a highly organized fibril structure both in vivo and in vitro. Here we use solid-state NMR on stable, homogeneous fibrils of A beta((10-35)) Specific interpeptide distance constraints are determined with dipolar recoupling NMR on Fibrils prepared from a series of singly labeled peptides containing C-13-carbonyl-enriched amino acids, and skipping no more that three residues in the sequence. From these studies, we demonstrate that the peptide adopts the structure of an extended parallel beta-sheet in-register at pH 7.4. Analysis of DRAWS data indicates interstrand distances of 5.3 +/- 0.3 Angstrom (mean +/- standard deviation) throughout the entire length of the peptide, which is compatible only with a parallel beta-strand in-register. Intrastrand NMR constraints, obtained from peptides containing labels at two adjacent amino acids, confirm the secondary structural findings obtained using DRAWS. Using peptides with C-13 incorporated at the carbonyl position of adjacent amino acids, structural transitions from alpha-helix to beta-sheet were observed at residues 19 and 20, but using similar techniques, no evidence for a turn could be found in the putative turn region comprising residues 25-29, Implications of this extended parallel organization for A beta((10-35)) for overall fibril formation, stability, and morphology based upon specific amino acid contacts are discussed.

This EOS can satisfactorily describe the thermodynamic properties of chain fluids both far-from and near-to the critical region; it is used here to calculate the critical locus of a mixture. Because the calculations require much computation time, especially for ternary land higher) mixtures, an interpolation method is used as suggested by Redlich over 30 years ago. For a binary mixture, along the critical line that gives the critical temperature or critical pressure as a function of composition, the limiting slopes at the critical points of the pure components are explicitly derived from the criteria for a critical point. Logarithmic-hyperbolic interpolation equations are selected to calculate the entire critical lines of the binary mixtures; this procedure is then generalized to multicomponent mixtures. Upon comparison with experimental critical data, the interpolation equations give good critical lines for binary and multicomponent type-1 mixtures of n-alkanes. (C) 2000 Elsevier Science B.V.

Progesterone signaling through progesterone receptor (PR) is essential for lobulo-alveolar development that accompanies pregnancy, but not far ductal growth accompanying puberty. PR exists in two molecular forms, A and B, and an imbalance in the native ratio of the two isoforms can lead to alterations in PR signaling. Indeed, as we reported previously, in transgenic mice carrying additional A form of PR, mammary development is abnormal, characterized by excessive lateral ductal branching. This suggests that alterations in PR signaling may have important consequences to mammary development, particularly with regard to ductal vs. alveolar growth. To test this further, we created transgenic mice carrying additional B form of PR and report that mammary development in these mice is also abnormal, characterized by inappropriate alveolar growth. More importantly, these mammary glands, on serial transplantation, undergo a premature arrest in ductal growth without any alteration in the potential for lobulo-alveolar growth. Such an arrest in ductal growth does not occur with transgenics carrying additional A farm of PR. These studies. therefore, provide strong evidence to indicate that PR signaling may be of paramount importance for appropriate cell-fate decisions during normal mammary development and also that this requires a regulated expression of the two isoforms.

In marked contrast to these slow global dynamics, hydrogen exchange experiments here demonstrate that conformational opening for solvent access occurs in the approximate to millisecond time frame or faster at 28 degrees C for all amide positions. Under these conditions all backbone amides with exchange protection factors between 10(4) and 10(6), for which EX2 exchange kinetics were directly verified, have exchange activation energy values within 2-3 kcal/mol of that observed for unstructured peptides. The conformational flexibility of this protein is thus sufficient for water and base catalyst access to the exchanging amide with quite limited structural disruption. The common hypothesis that enhanced conformational rigidity in the folded native state underlies the increased thermal stability of hyperthermophile proteins is not supported by these data.

This communication uses the completed genomes from four major euryarchaeal taxa to define a genomic signature for the Euryarchaeota and, by extension, the Archaea as a whole. The signature is defined in terms of the set of protein-encoding genes found in at least two diverse members of the euryarchaeal taxa that function uniquely within the Archaea; most signature proteins have no recognizable bacterial or eukaryal homologs. By this definition, 351 clusters of signature proteins have been identified. Functions of most proteins in this signature set are currently unknown. At least 70% of the clusters that contain proteins from all the euryarchaeal genomes also have crenarchaeal homologs. This conservative set, which appears refractory to horizontal gene transfer to the Bacteria or the Eukarya, would seem to reflect the significant innovations that were unique and fundamental to the archaeal "design fabric." Genomic protein signature analysis methods may be extended to characterize the evolution of any phylogenetically defined lineage. The complete set of protein clusters for the archaeal genomic signature is presented as supplementary material (see the PNAS web site, www.pnas.org).

H-2 production is enhanced in a second catalytic reactor through the water gas shift reaction, in which the CO reacts with steam that is injected into the reactor at a controlled rate to produce CO2 and H-2. Experiments and thermodynamic calculations were used to establish the optimal lower temperature (approximate to 400 degrees C) and lower steam-to-CO ratio (approximate to 2) to achieve thermodynamic efficiency while maximizing H-2 production. No unusual synergisms were observed by the combination of the two processes and the experimental results are in good agreement with thermodynamic predictions. (C) 2000 Elsevier Science B.V.

Hydrogen gas is introduced during film growth in order to reduce or eliminate the presence of the GeO2 from the semiconductor surface during the initial nucleation of the metal-oxide film. The hydrogen partial pressure and substrate temperature are selected to be sufficiently high such that the germanium native oxides are thermodynamically unstable. The Gibbs free energy of CeO2 is larger in magnitude than that of the Ge native oxides, making it more favorable for the metal-oxide to reside at the interface in comparison to the native Ge oxides. By satisfying these criteria, the metal-oxide/semiconductor interface is shown to be atomically abrupt with no native oxide present. (C) 2000 American Institute of Physics. [S0003-6951(00)04413-2].

In the p-type material alone, a characteristic peak in the resistivity rho(T,H) is dramatically enhanced and moves to higher temperature with increasing magnetic field, resulting in a high field (H similar to 5 T) magnetoresistance that is sizeable even at room temperature. By contrast, n-type specimens are geared for low-field (H < 0.1 T) applications because of a striking linear field dependence of the magnetoresistance that appears to be restricted to the Ag-rich materials.

This change in microstructure was found to have a large effect on coercivity, i.e., coercivity, mu(0)H(c), increases with an increase of the Nd concentration from 1.25 T in Nd2.05Fe13.1B to 2.75 T in Nd147.6Fe13.1B at 290 K. Using transmission electron microscopy, the Nd2Fe14B grains in Nd147.6Fe13.1B were confirmed to be randomly oriented platelets with the c axis normal to the plate and an average size of 100 x 40 x 25 nm. For these randomly oriented, noninteracting, single domain Nd2Fe14B grains, the coercivity was calculated using a Stoner-Wohlfarth model which included the shape anisotropy of the grains. The observed coercivity of Nd2Fe14B in such nanocomposite Nd147.6Fe13.1B alloys is similar to 83% of its theoretical value. (C) 2000 American Institute of Physics. [S0003-6951(00)00513-1].

Strong alignment of adjacent grains was found to be necessary from previous work that suggested large angle, YBa2Cu3O7-delta [001]-tilt boundaries reduce J(c) exponentially with increasing misorientation angle (theta). We pursue the low-theta regime by evaluating single grain boundaries (GB) and biaxially aligned polycrystalline films utilizing both the rolling-assisted biaxially textured substrates and ion-beam assisted deposition coated conductor architectures. Analysis concludes that an exponential dependence on J(c) is applicable for theta greater than or similar to 4 degrees, where the spacing between the periodic disordered regions along the GB become smaller than a coherence length.

The experiment was conducted at the Rocket Triggered Lightning Program facility at Cape Canaveral, Florida, in August 1991, during the Convection and Precipitation/Electrification field experiment. Plumes of NOx from spark generations were sensed by a NOx analyzer. The spark energy was 9.8 +/- 0.7 X 10(4) J, and the spark gap was 1.65 or 2.13 m. The plumes reached the analyzer inlet within 0.3-4.7 s after spark generation. The lq, concentrations varied, depending on the geometry of the plume. Laboratory studies of analyzer response permitted adjustment of the measured concentrations to corrected concentrations. Production of NOx, in terms of mass of nitrogen, averaged 22.5 +/- 2.9 mg per spark, 11.7 +/- 1.5 mg m(-1) of spark length, and 1.1 +/- 0.2 x 10(16) molecules J(-1). The median ratio of nitric oxide (NO) to nitrogen dioxide (NOx) was 0.76, indicating substantial conversion within a few seconds. Scaling of NO production to lightning energy levels and dimensions yielded an annual global NOx production of 9.7 Tg yr(-1), similar to values estimated from recent thunderstorm measurements and modeling studies. Recent satellite measurements suggest that cloud-to-ground lightning flash frequency is an order of magnitude smaller than normally assumed; estimates of global NOx production by lightning might also need to be reduced by an order of magnitude.

It also considers statistical issues that arise in assessing the significance of individual trends and of trend differences between data sets. Possible causes of these trends are not addressed. We use data from satellite and radiosonde measurements and from two reanalysis projects. To facilitate intercomparison, we compute from reanalyses and radiosonde data temperatures equivalent to those from the satellite-based Microwave Sounding Unit (MSU). We compare linear trends based on minimization of absolute deviations (LA) and minimization of squared deviations (LS). Differences are generally less than 0.05 degrees C/decade over 1959-1996. Over 1979-1993, they exceed 0.10 degrees C/decade for lower tropospheric time series and 0.15 degrees C/decade for the lower stratosphere. Trend fitting by the LA method can degrade the lower-tropospheric trend agreement of 0.03 degrees C/decade (over 1979-1996) previously reported for the MSU and radiosonde data. In assessing trend significance we employ two methods to account for temporal autocorrelation effects. With our preferred method, virtually none of the individual 1979-1993 trends in deep-layer temperatures are significantly different from zero. To examine trend differences between data sets we compute 95% confidence intervals for individual trends and show that these overlap for almost all data sets considered. Confidence intervals for lower-tropospheric trends encompass both zero and the model-projected trends due to anthropogenic effects. We also test the significance of a trend in d(t), the time series of differences between a pair of data sets. Use of d(t) removes variability common to both time series and facilitates identification of small trend differences. This more discerning test reveals that roughly 30% of the data set comparisons have significant differences in lower-tropospheric trends, primarily related to differences in measurement system. Our study gives empirical estimates of statistical uncertainties in recent atmospheric temperature trends. These estimates and the simple significance testing framework used here facilitate the interpretation of previous temperature trend comparisons involving satellite, radiosonde, and reanalysis data sets.

These energies are all compared against a common reference, the energy of incoherent phase separation (the composition-weighted energy of the constituents each at their own equilibrium volumes). Unlike long-range order (LRO), short-range order is determined by energetic competition between phases at a fired composition, and hence only coherent phase-separated states are of relevance for SRO. We find five distinct SRO types, and give examples showing each of these five types, including Cu-Au, AI-Mg, GaP-InP, Ni-Au, and Cu-Ag. The SRO is calculated from first principles using the mixed-space cluster expansion approach combined with Monte Carlo simulations. Additionally, we examine the effect of inclusion of coherency strain in the calculation of SRO, and specifically examine the appropriate functional form for accurate SRO calculations.

The standard picture, in which the inner tetrahedron of(S = 3/2) Mn4+ ions is polarized antiparallel to an outer ring of eight (S = 2) Mn3+ ions, is confirmed directly. While the total magnetization for the molecule is in good agreement with bulk measurements, the individual moment components on each of the three symmetry-independent Mn sites are less than predicted by the standard picture. There is no evidence for net moments on the oxygen atoms, but overlap of positive and negative magnetization on the oxygen sites cannot be ruled out.

Recently, these have been combined with x-ray diffraction at synchrotron sources to provide structural information not previously available. This article reviews and summarizes recent results obtained from x-ray diffraction on levitated liquid materials in both the normal and supercooled states. In particular, it addresses the effects of supercooling on the short-range structure, including interatomic distances and coordinations, of several high-temperature molten oxides, semiconductors and metallic materials. The properties of these liquids are discussed in the context of available molecular dynamics simulations and thermophysical property data. C1 Containerless Res Inc, Evanston, IL 60201 USA.

It is designed to accommodate effective nucleon-nucleon (NN) interactions that depend upon the density of nuclear matter in which the two nucleons are immersed. A recently parametrized density dependent M3Y interaction, based on the G-matrix elements of the Pails NN potential, has been used in the present folding calculation. The effects of knock-on exchange of the interacting nucleon pair are included in an accurate local approximation, Examples of the application of this model to study the refractive elastic and inelastic scattering data of C-12 + C-12 and alpha + Ni-58.60 systems are presented. A detailed comparison of the use of deformed optical potential (DP) and microscopic folded potential in the analysis of inelastic scattering has shown that the use of DP fails to reproduce the inelastic C-12 + 12C scattering das measured over a wide angular range, which covers both the diffractive and refractive regions. The use of the DP model also significantly underestimates the nuclear deformation lengths of the quadrupole and octupole excitations under study. (C) 2000 Elsevier Science B.V. All rights reserved.

Zylberstejn, A CA D0 Collaboration TI Isolated photon cross section in p(p)over-bar collisions at root s=1.8 TeV SO PHYSICAL REVIEW LETTERS LA English DT Article AB We report a new measurement of the cross section for the production of isolated photons with transverse energies (E-T(gamma)) above 10 GeV and pseudorapidities \eta\ < 2.5 in p (p) over bar collisions at root s = 1.8 TeV. The results are based on a data sample of 107.6 pb(-1) recorded during 1992-1995 with the D0 detector at the Fermilab Tevatron collider. The background, predominantly from jets which fragment to neutral mesons, was estimated using the longitudinal shower shape of photon candidates in the calorimeter. The measured cross section is in good agreement with the next-to-leading order QCD calculation for E-T(gamma) greater than or similar to 36 GeV. C1 NYU, New York, NY 10003 USA.

transverse momentum distribution of Z bosons produced in p (p) over bar collisions at root s = 1.8 TeV from data collected by the DO experiment at the Fermilab Tevatron Collider, We find good agreement between our results and current resummation calculations, and also use our data to extract nonperturbative parameters for a particular version of the resummation formalism. The resulting values are significantly more precise than obtained in previous determinations. C1 NYU, New York, NY 10003 USA. Univ Buenos Aires, Buenos Aires, DF, Argentina.

The sensitivity of the multidimensional correlation functions to the geometry and dynamics of the pion-emitting system provides a stringent test of transport models of heavy ion collisions. Detailed comparisons with a realistic transport model, both with and without an explicit nuclear mean field, suggest that the beam energy evolution in the reaction dynamics is different in the model than in the data. A significantly increased pi(-) emission time scale, which has been suggested as a signal of the onset of the transition to quark-gluon plasma, is not observed.

The strength of this process shows an unexpectedly strong species dependence. We find that this dependence can be explained via the difference in the cross section for electron-ion scattering from the different atoms. This allows us to directly relate the high energy portion of the photoelectron spectrum to specific features of the electron-ion potential. C1 Lund Inst Technol, Dept Phys, S-22100 Lund, Sweden.

Both products of the instability, the ion acoustic wave and the electron plasma wave, were simultaneously observed and identified with their spectral characteristics. The secondary decay of the LDI-generated electron plasma wave, into another Langmuir wave and an ion acoustic wave, has been observed for the first time. The connection with growth and saturation of the stimulated Raman instability is discussed.

Pronounced differences from the corresponding atom intensity on the flat surface are observed for the contrast of atoms on the low versus the high side of the step and for the contrast between the faulted versus unfaulted subcells of the (7 x 7) structure. These differences can be accounted for by changes in the electronic structure within the (7 x 7) subcells adjacent to the step. Calculations of the local density of states and the STM images using a tight-binding method are in excellent agreement with the experimental results.

Substitutionally doped boron or nitrogen produces quasibound impurity states of a definite parity and reduces the conductance by a quantum unit (2e(2)/h) via resonant backscattering. These resonant states show strong similarity to acceptor or donor states in semiconductors. The Stone-Wales defect also produces quasibound states and exhibits quantized conductance reduction. In the case of a vacancy, the conductance shows a much mon complex behavior than the prediction from the widely used pi-electron tight-binding model.

This is accompanied by a tetragonal to orthorhombic distortion. Below 220 K orbital ordering and long-range Co2+/Co3+ charge ordering occur as well as a change in the Co2+ spin state from low to high spin. This transition is shown to be very sensitive to the oxygen content of the sample. To our knowledge this is the first observation of a spin-state transition induced by long-range orbital and charge ordering. C1 Brookhaven Natl Lab, Dept Phys, Upton, NY 11973 USA.

It is based on the observation of an exponential growth in time of the proton NMR signal during the thermal equilibration of the magnetization of the molecules, We can explain the novel effect with a simple model which relates the intensity of the proton echo signal to the microscopic reversal of the magnetization of each individual Mn12 molecule during the equilibration process.
