The results showed that the Cu-5 pct Nb alloy was transformed into a composite material with the original Nb dendrites becoming ribbonlike filaments in a similar fashion to higher Nb-containing Cu-Nb alloys. The degree of strength increase with increasing deformation processing greatly exceeds rule-of-mixtures expectations at higher degrees of deformation processing, where the Nb becomes highly aligned with the wire axis. A 5 pct Nb addition appears to contain close to the minimum amount of Nb phase necessary to produce appreciable strengthening during deformation processing of Cu-Nb alloys. The strength-conductivity properties of the deformation-processed Cu-5 pct Nb alloy show significant improvements in strength over the best commercial alloys in the conductivity ran-e of 80 to 90 pct international annealed copper standard (IACS).

The powders were classified, and a larger size fraction, whose microstructure consisted mainly of 0.4-mum-diameter Nb dendrites, was fabricated into the precursor billet by powder metallurgical techniques. The deformation-processed wire prepared from the powder alloy billet gave significantly increased strengths at a given level of deformation strain over similar material produced by consumable arc casting. This may bc attributed to the smaller initial Nb dendrite size of the alloy powder used for the precursor billet. However, the electrical conductivity of the powder material at a given strength level was significantly lower than the arc-cast material. The cause of the reduction of the conductivity is uncertain, and possible reasons are discussed. C1 IOWA STATE UNIV SCI & TECHNOL,AMES LAB,AMES,IA 50011. DRAKE UNIV,DES MOINES,IA 50311.

It has been demonstrated that by (1) using high-purity gas-atomized Cu powders blended with commercial high-purity Fe powders and (2) controlling the time/temperature processing conditions within specific limits, it is possible to produce Cu-Fe deformation-processed alloys with strength/conductivity properties matching those of Cu-Nb, Cu-Ta, and Cu-Cr alloys.

These materials had been processed to contain either chloride inclusions or pores or a combination of both types of defects. The fracture toughness values for all of the samples were inversely dependent on the volume fraction of defects. These values also depended on defect type, with toughness values that were significantly higher in material containing only pores than in material containing inclusions or inclusions and pores. In all samples, fracture occurred by microvoid coalescence which initiated at these defects. Quantitative fractography and a ductile fracture toughness model were then combined to further define the relationship between defects, fracture mode, and fracture toughness. This approach showed that the smallest inclusions did not participate in the fracture process. Of the defects that did participate, the approach showed that both chloride inclusions and pores control fracture toughness in all alloys studied through their effects on defect spacing and the amount of void growth to failure. Furthermore. it demonstrated that the only alloy in which the pores and chloride inclusions combined to control fracture toughness was Ti-10V-2Fe-3Al.

Processing with a single pulse results in the transformation of the alpha + beta material to alpha' martensite. Multiple pulse processing results in rapid incorporation of oxygen in the material. Oxygen initially dissolves in the material in the liquid phase. As the concentration exceeds the solid solubility limit during solidification, TiO particles precipitate. In contrast to equilibrium oxidation processes in Ti, only TiO is observed as an oxidation product; further processing results in increased oxygen incorporation and an increased volume fraction of TiO but no other oxides of Ti. The TiO particle size is a function of the oxygen concentration and the number of pulses, with some grain growth occurring after many pulses. The effects of solution hardening by dissolved oxygen and precipitation hardening by the TiO are identifiable as functions of oxygen concentration and mean free path between particles, respectively. A maximum surface hardness almost twice that of electropolished Ti-6Al-4V is observed. C1 LOS ALAMOS NATL LAB,DIV NUCL MAT TECHNOL,LOS ALAMOS,NM 87545.

These basaltic aquifers were alkaline (pH 8.5 to 10.5) and anaerobic (Eh - 200 to - 450 mV). The wells were allowed to free-flow until pH and Eh stabilized, then the microflora was sampled with water filtration and flow-through sand-trap methods. Direct microscopic counts showed 7.6 x 10(5) and 3.6 x 10(3) bacteria ml-1 in water from the Grande Ronde and Priest Rapids aquifers, respectively. The sand filter method yielded 5.7 x 10(8) and 1.1 X 10(5) cells g-1 wet weight of sand. The numbers of bacteria did not decrease as increasing volumes of water were flushed out. The heterotrophic diversity of these bacterial populations was assessed using enrichments for 20 functional groups. These groups were defined by their ability to grow in a matrix of five different electron acceptors (O2, Fe(III), NO3-, SO42-, HCO3-) and four groups of electron donors (fermentation products, monomers, polymers, aromatics) in a mineral salts medium at pH 9.5. Growth was assessed by protein production. Culture media were subsequently analyzed to determine substrate utilization patterns. Substrate utilization patterns proved to be more reliable indicators of the presence of a particular physiological group than was protein production. The sand-trap method obtained a greater diversity of bacteria than did water filtration, presumably by enriching the proportion of normally sessile bacteria relative to planktonic bacteria. Substrate utilization patterns were different for microflora from the two aquifers and corresponded to their different geochemistries. Activities in the filtered water enrichments more closely matched those predicted by aquifer geochemistry than did the sand-trap enrichments. The greatest activities were found in Fe(III)-reducing enrichments from both wells, SO4-reducing enrichments from the Grande Ronde aquifer, and methanogenic enrichments from the Priest Rapids aquifer. Organisms from these aquifers may be useful for high-pH bioremediation applications as well as production of biotechnological products. These organisms may also be useful for modeling potential reactions near buried concrete, as might be found in subsurface waste depositories.

As-grown CdS films were polycrystalline with a grain size in the 200-600 Angstrom range. Significant grain growth and reduction in defect density were observed in these films after heat treatment. The CdTe films exhibited a high density of grain boundaries and structural defects within the grains. Both grain boundaries and intragrain defects are very active recombination sites. Heat treatment effected a marked grain growth and reduction in the recombination efficiency of the grain boundaries and intragrain defects.

Highly hydrophobic, No. 2 Gas Seam coal from West Virginia and moderately hydrophobic, Colchester Seam coal from Illinois were agglomerated with hexadecane in a series of tests in which oil dosage was varied as well as the pH and salt concentration of the aqueous medium. Changes in the aqueous medium had the greatest effect on the rate of agglomeration when the oil dosage was a minimum. The rate of agglomeration was a maximum at pH 9 for No. 2 Gas coal and at pH 4 for Colchester coal. Between pH 9 and 12, the rate of agglomeration of Colchester coal decreased markedly for any oil dosage, whereas the rate of agglomeration of No. 2 Gas coal declined less noticeably except al the lowest oil dosage. The rate of agglomeration of both coals increased when the ionic strength was increased. However, the effect was much greater on No. 2 Gas coal than on Colchester coal.

The gene encodes a protein of 116 kDa (p116) and has significant homology to another yeast gene (XRN1/KEM1) encoding a related protein (p175) with 5'-->3' exonuclease activity as well as activities involving chromosomal DNA pairing and mechanics. Preliminary analysis of an hke1ts mutant reveals a precipitous decline in the translation of mRNA at the nonpermissive temperature. Sporulation of heterozygous HKE1/hke1::URA3 diploids reveals that this gene, unlike the highly related XRN1/KEM1 gene, is essential for cell viability. Overexpression of the homologous gene product, p175, failed to rescue cells lacking a functional p116. In vitro studies demonstrate that p116 is a protein with 5'-->3' exoribonuclease activity, a major activity of the related p175. An immunoreactive RNase activity of 116 kDa is abolished with antiserum against p116. Both the level of this protein and the RNase activity correlate with HKE1 gene dosage. The RNase activity purifies coincidentally with a previously described 116-kDa RNase having 5'-->3' exoribonuclease activity.

Inducible antibody and antibody-like responses are found in all vertebrates. However, immunoglobulin possessing disulfide-bonded heavy and light chains and domain-type organization has been described only in representatives of the jawed vertebrates. High degrees of nucleotide and predicted amino acid sequence identity are evident when the segmental elements that constitute the immunoglobulin gene loci in phylogenetically divergent vertebrates are compared. However, the organization of gene loci and the manner in which the independent elements recombine (and diversify) vary markedly among different taxa. One striking pattern of gene organization is the ''cluster type'' that appears to be restricted to the chondrichthyes (cartilaginous fishes) and limits segmental rearrangement to closely linked elements. This type of gene organization is associated with both heavy- and light-chain gene loci. In some cases, the clusters are ''joined'' or ''partially joined'' in the germ line, in effect predetermining or partially predetermining, respectively, the encoded specificities (the assumption being that these are expressed) of the individual loci. By relating the sequences of transcribed gene products to their respective germ-line genes, it is evident that, in some cases, joined-type genes are expressed. This raises a question about the existence and/or nature of allelic exclusion in these species. The extensive variation in gene organization found throughout the vertebrate species may relate directly to the role of intersegmental (V<->D<->J) distances in the commitment of the individual antibody-producing cell to a particular genetic specificity. Thus, the evolution of this locus, perhaps more so than that of others, may reflect the interrelationships between genetic organization and function. C1 UNIV S FLORIDA,DEPT PEDIAT,TAMPA,FL 33620.

From 3 to 144 h after treatment with CCl4 the livers of FVB/N mice were analyzed for specific nuclear protein binding to the LTR DNA. Three to nine hours after CCl4 treatment, decreased protection was seen at potential regulatory cis-elements throughout the LTR, including specific sites within the putative negative regulatory element (located 5' of the consensus enhancer sequences) and the 3' terminal portion of the polytropic class-specific enhancer-like inserted sequence element and around the CCAA(C/T) box in the promoter region. In addition, by 3-6 h after treatment, a transient increase in protection activity for the transcription initiation site occurred. The loss of cis-element protection expanded to other binding sites and became most marked by 48 h after treatment. As the regenerating liver recovered, the nuclear protein binding activities for these LTR sequences also recovered, but protection at the TATAA and transcription initiation sites remained deprotected at 144 h after treatment. Nuclear protein protection of other sites, particularly in the conserved LTR enhancer sequences, was minimally affected by CCl4 treatment. Three nuclear protein binding sites that showed rapid CCl4-induced kinetic changes were homologous to the consensus sequence for the binding of the transcription factor families MEF-2, HNF-1, and C/EBP. The complex kinetic changes in factors that may contribute to the rapid and transient induction of endogenous retroviral gene expression in the fiver after CCl4 exposure are discussed.

Entropies are measured through a range of concentrations, independently of whether these configurations represent equilibrium conditions. Rod concentrations, orientation distribution shapes, and order parameters that are expected to be present at equilibrium can then be determined by comparing free energy curves. The method was applied to two-dimensional, monodisperse, athermal systems and the results demonstrated that choice of the shape of the global orientation distribution in the anisotropic phase can result in shifting from a first-order to a continuous isotropic-to-nematic phase transition.

The comparison is made for two-dimensional, monodisperse, athermal systems. For this purpose, we have adapted the Flory-Ronca model to two dimensions, gaining additional insight into the justification for one of the numerical correction factors used in that model. The CMC and DLM approaches both predict that a uniform (flat) distribution of rod orientations in the anisotropic phase is associated with a first-order isotropic-to-nematic transition, while normally distributed orientations lead to a continuous transition with increasing rod concentration. The two models also agree qualitatively with respect to the relative free energies of different rod orientation distributions in the anisotropic phase. However, the DLM assigns disproportionately high entropy to short rods (especially at high concentrations) and to disordered phases, so that the DLM does not generate quantitatively reliable phase diagrams.

The DLM allows rods to cross, enables rods to fit too easily into tight spaces, does not account for unoccupiable (wasted) space, and neglects the ingrowth of short-range order. Increasing resolution can eliminate the first two shortcomings from the DLM. To account for wasted space in the DLM, it will be necessary to derive a more complex expression for combinatoric entropy. To properly accommodate the effect of short-range order, the calculation of both combinatoric and orientational entropy must be improved. C1 UNIV WASHINGTON, CTR BIOENGN, SEATTLE, WA 98195 USA.

The compounds analyzed were (C3H7)4NBr, (C4H9)4NBr, (C5H11)4NBr, (C6H13)4NBr, (C7H15)4NBr, (C8H17)4NBr, (C10H21)4NBr, (C12H25)4NBr, (C16H33)4NBr, (C18H37)4NBr, (C3H7)4NI, (C4H9)4NI, (C5H11)4NI, (C6H13)4NI, (C7H15)4NI, and (C12H25)4NI. The total vibrational contribution to the heat capacity is thus, derived and compared to the experimentally measured heat capacity over the whole temperature range. Positive deviations of the measured heat capacity from the calculation occur already below room temperature, implying the existence of large-amplitude, nonvibrational motion in the solid state, as suggested before by solid-state C-13 NMR analysis. Quantitative information on the entropy of disordering generated outside of the transition ranges is derived and agrees with the entropy deficits predicted by the analysis of the first-order transitions. An addition scheme is developed for the heat capacity of the methylene groups in these compounds, that is similar to the paraffins. C1 OAK RIDGE NATL LAB,DIV CHEM,OAK RIDGE,TN 37831.

It is proven that this group of molecules cannot form plastic crystals. Their mesophases show only conformational disordering of C-C single bonds below isotropization. In most cases, the observed phase transitions in calorimetry can be correlated with abrupt changes of the chemical shift of certain carbon atoms in the alkyl chains. The bonds at the chain ends tend to become gradually conformationally mobile and disorder at temperatures much below the first observable transition. The increased mobility is revealed by a gradual up-field shifting of the resonance peaks with increasing temperature. This feature explains the entropy deficit in total entropy of fusion observed by calorimetry. Crystal structure changes can be coupled with a possible change in the nitrogen-to-anion distance, as shown by significant chemical shift changes of the inner-most carbon atoms. Orientational and positional disordering is only possible on isotropization (final step of melting). C1 OAK RIDGE NATL LAB,DIV CHEM,OAK RIDGE,TN 37831.

A recent report by Merzhanov et al. [C. R. Acad. Sci., Paris, 314, 563 (1992)] has shown that this same C-13 substitution leads to a ''giant'' isotope effect (DELTAT(c) = -0.6 K) in resistive determinations of T(c) (approximately 8 K) for beta*-(ET)2I3, which lends experimental support to a theory by Yamaji [Solid State Commun., 61, 413. (1987)] for salts of TTF-analogue donor molecules that includes optical phonons of symmetric intramolecular vibrations as a source of mediation for superconducting pairing of charge-carriers. In contrast to this result, our study shows the absence of an isotope effect within a precision of +/- 0.1 K (approximately 1%), indicating that the central atom C=C stretching motion (approximately 1500 cm-1) of ET cannot be a dominant mechanism for phonon exchange. Our results are consistent with those of a very recent study of the same isotope effect for kappa-(ET)2Cu[N(CN)2]Br and kappa-(ET)2Cu(NCS)2 [Inorg. Chem., 32, 3356 (1992)].

The full-length alfalfa GS1 coding sequence, in both sense and antisense orientation and under the transcriptional control of the cauliflower mosaic virus 35S promoter, was introduced into tobacco. Leaves of tobacco plants transformed with the sense construct contained greatly elevated levels of GS transcript and GS polypeptide which assembled into active enzyme. Leaves of the plants transformed with the antisense GS1 construct showed a significant decrease in the level of both GS1 and GS2 polypeptides and GS activity, but did not show any significant decrease in the level of endogenous GS mRNA. We have proposed that antisense inhibition using a heterologous antisense GS RNA occurs at the level of translation. Our results also suggest that the post-translational assembly of GS subunits into a holoenzyme requires an additional factor(s) and is under regulatory control.

The resulting mutant strain was found to be a strict 5-aminolevulinic acid (ALA) auxotroph, to be nitrogen-fixation proficient in culture (Nif+) and to induce ineffective, nitrogen fixation-deficient (Fix-) root nodules, lacking leghemoglobin, on Sesbania rostrata. Moreover, the hemA::Tn5 A. caulinodans mutant (ALAS122) was found to be unable to induce stem-nodules on S. rostrata (Nod-). Second-site suppressor mutations, capable of growing on full medium (TY) in the absence of additional ALA, were isolated (ALAS122RT strains). hemA::Tn5 strains carrying these secondary mutations were found to be disturbed in free-living nitrogen fixation (Nif- to Nif+/-) and in some cases in nitrogen assimilation (Ntr-/+), but displayed the same symbiotic phenotype as the original hemA::Tn5 strain (Fix- on roots; Nod- on stems). The Ntr-/+ phenotype of the ALAS122RT strains could be complemented by plasmids carrying the ntrC and/or ntrYX loci of A. caulinodans, suggesting a role for the ntr system in controlling the activation of a (normally cryptic) secondary ALA biosynthesis pathway in strains carrying the second-site suppressor mutations. Growth of the ALAS122RT strains on TY medium lacking ALA was found to be inhibited significantly by inhibitors of the C5 ALA synthesis pathway, such as gabaculine and amino-oxyacetate (AOA), suggesting the possibility that both the Shemin and C5 ALA synthesis pathways may exist in A. caulinodans.

To evaluate the configurational energy of a system of molecules, commonly used experessions describe the interaction between two molecules. Contributions from higher-body forces are usually implicitly taken into account by adjusting two-body potential parameters to give agreement with experimental data. Explicit expressions for higher-body potentials are not commonly used in simulations [8]. The work by Smit et al. [9] gives the appropriate expressions to evaluate the pressure as well as the chemical potential from a density-dependent two-body potential in an NVT ensemble. In the present work, contributions to the potential from two-body interactions are separated from those due to higher-body interactions; to take higher-body forces into account, a mean-field term, proportional to (density)0.9, is added to the two-body potential. NPT-simulations over a wide range of temperature and density, as well as Gibbs-ensemble simulations, are used to evaluate phase behavior of argon and of methane. The results indicate that a simple mean-field correction to the ''true'' two-body Kihara potential provides good agreement between experiment and simulation.

During the- first and last phases the subjects refrained from eating cooked meat for 4-5 days. This was designed to clear their system of mutagens found in cooked-meat products. In the second phase each person ate a similar diet, but also consumed 4 quarter-pound well-done hamburgers per day for 4 days. Erythrocyte-folate levels were also measured for each donor. No association between diet phase and micronucleus frequencies was observed among the 2 subjects with normal levels of folate. However, among the 3 low-folate donors, the frequency of micronucleated PCEs appeared to be associated with diet. Micronucleus frequencies began to increase 1 day following onset of the beef phase, and started to decline 1 day after finishing this phase. These observations are in agreement with erythrocyte maturation kinetics following short-term exposure. A repeat study performed on one of the low-folate donors consisted of two beef phases separated by a vegetarian phase. Beef in one phase was fried (high in mutagenic amino-imidazoazaarenes [AIAs]) while the beef in the other phase was fried after first being microwave-cooked (low in AIAs). Significant increases in the micronucleus frequency were not observed in this experiment, suggesting that AIAs formed during frying were not solely responsible for the induction of micronuclei.

The yield of neither radiation-induced DNA single- nor double-strand breaks could explain the variable sensitivity of the 3 cell lines. Closure of DNA single-strand breaks proceeded at a similar rate in both the L and SL3-147 cell lines. Closure of DNA double-strand breaks however was significantly slower and less complete in the SL3-147 cell line than in either of the radiation-resistant cell lines. The results are consistent with the increased radiation sensitivity of the SL3-147 cell line resulting from a defect in their ability to repair radiation-induced DNA double-strand breaks.

Marrow was collected prior to the initiation of treatment in patients with sarcoma or testicular cancer; marrow was collected after initial cytoreductive therapy for patients with non-Hodgkin's lymphoma, Hodgkin's disease, and other tumors. Slot-blot analysis of marrow RNA showed a bimodal pattern of ERCC1, ERCC2 and ERCC6 gene expression with relative expression values ranging more than 200-fold. This pattern was seen in all patient groups and appeared to be independent of whether or not patients had received prior chemotherapy. In all patient groups, when expression was low for ERCC1, expression was also low for ERCC2 and ERCC6, suggesting that expression of these genes may be coordinated within an individual although they are located on two different chromosomes. Southern blot analyses of Pst I digests of DNA from 6 bone-marrow samples indicate no differences in ERCC1 gene copy number between high expressors and low expressors. There is absence of restriction fragment length polymorphism for ERCC1 suggesting that the different levels of expression in high and low expressors were not due to major deletions or rearrangements of the ERCC1 gene. We conclude that expression of these ERCC genes may vary widely between individuals, and that within an individual, their expression may be linked and coordinated by a common regulatory mechanism.

We discuss a clustering strategy that explicitly reflects the tradeoff between simplicity and precision of a data representation. The resulting clustering algorithm jointly optimizes distortion errors and complexity costs. A maximum entropy estimation of the clustering cost function yields an optimal number of clusters, their positions, and their cluster probabilities. Our approach establishes a unifying framework for different clustering methods like K-means clustering, fuzzy clustering, entropy constrained vector quantization, or topological feature maps and competitive neural networks.

This problem arose in the 1970s, and until recently the only cases for which efficient algorithms were found were for binary (i.e. two-state) characters and for two characters at a time, while the complexity of the general problem remained open. In this paper we will discuss the remarkable progress on this problem since 1990. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

This code is a general 6D relativistic design code with a MAD compatible input language and among others implements user defined functions and subroutines and nested fitting and optimization. First we describe the mathematics and physics in the code. Aside from generating maps for all the standard accelerator elements we describe an efficient method for generating nonlinear transfer maps for realistic magnet models. We have implemented the method to arbitrary order in our accelerator design code for cylindrical current sheet magnets. We also have implemented a self-consistent space-charge approach as in CHARLIE.

Our approach is based on representing the accelerating electric field with a continuous phase modulated traveling wave. The resulting nonlinear equations of motion can be solved analytically to predict the regions of stable APF motion. We also identify the key parameters which adequately describe the physics of APF. The model is believed to be applicable to low-P ion linacs with short independently-controlled superconducting cavities being developed at ANL.

Further, for the first time, an (m, n) = (1, 1) 'cold bubble' precursor to high density disruptions has been experimentally observed in the electron temperature profile. The precursor to major disruptions resembles the 'vacuum bubble' model of disruptions first proposed by B.B. Kadomtsev and O.P. Pogutse (Sov. Phys. - JETP 38 (1974) 283).

The fluctuations in the ion saturation current (I(s)/I(s)) and the transport inferred from the fluctuations increase with increasing density gradient, while the local electron temperature is kept unchanged. The modification of the electron temperature in the range 10-50 eV while keeping the density profile constant does not have any significant influence on I(s)/I(s). In regions where E(r)/B almost-equal-to 0, the poloidal phase velocity of the fluctuations is given by v(ph) almost-equal-to 2T(e)/L(n)B.

ASSOCIATED EQUIPMENT LA English DT Article ID ELECTRON RESPONSE; HADRON; RESOLUTION; SIMULATION; LEAD AB We describe the results of beam tests of three uranium-liquid argon calorimeter modules constructed for the DO detector at the Fermilab Tevatron collider. As part of the calibration procedure, these modules were exposed to beam of electrons, pions and muons between 10 and 150 GeV / c before their installation in the end calorimeter of the completed DO detector. We obtain an electromagnetic sampling resolution of 15.7% / square-root E and constant term of 0.3%. The hadronic sampling resolution is 45% / square-root E (degraded to 50% / square-root E by the effects of upstream material) and the constant term is 4%. The calorimeter is linear to 0.5%, and the electromagnetic to hadronic response ratio is between 1.02 and 1.09 over this range of momenta. For an electron efficiency of 95% we obtain a rejection factor against pions of approximately 900-3000 for particles in the momentum range between 50 and 150 GeV / c. We also compare our results with the predictions of a detailed Monte Carlo simulation. C1 BROOKHAVEN NATL LAB,UPTON,NY 11973. BROWN UNIV,PROVIDENCE,RI 02912. UNIV CALIF RIVERSIDE,RIVERSIDE,CA 92521.

The current device, known as IMB-3, enjoys a factor of four light collection advantage over its precursor. Since May 1986, it has been used to search for such diverse phenomena as nucleon decay, dark matter, neutrino oscillation, and magnetic monopoles, and to study stellar collapse and cosmic rays. Due to its large size and long exposure time IMB presents unique challenges. The design and operation of the IMB-3 detector are described in detail. C1 UNIV MICHIGAN,ANN ARBOR,MI 48109.

However, the design basis and design processes for light-water containments have not generally been explicitly linked to accommodating these extreme events into the containment design. For light-water reactors (LWRs), the containment design has been based on considerations other than severe accidents, including the consideration of the containment during a loss-of-coolant accident. The resulting containment designs for certain pressurized LWRs were then assessed and shown to have adequate resistance to severe accidents. The LWR containment design basis would not be directly applicable for the New Production Reactor-Heavy Water Reactor (NPR-HWR) because of the low stored energy of the HWR. The Department of Energy's Office of New Production Reactors established a fundamental policy that the NPR-HWR containment would be designed under the following requirements: The NPR-HWR containment would be designed to accommodate hypothetical severe accident challenges. A full-scope probabilistic analysis of reactor operations, including severe accidents, would be performed to complement deterministic analyses and demonstrate containment adequacy. The defense-in-depth philosophy would be fully integrated into the containment design. The implementation of these and other requirements relevant to the containment design basis is being accomplished in a systematic manner for the NPR-HWR. Deterministic Severe Accident Criteria [(DSACs), a plural of the term Deterministic Severe Accident Criterion], a significant element of the integrated strategy for design consideration of severe accidents, have been established by the Office of Heavy Water Reactor to ensure that the containment is designed to withstand a wide spectrum of severe accident challenges.

For a practical implementation of high-level programmatic goals, these DSACs represent a new approach because they address severe accidents early in the design phase of the nuclear plant. This article describes a process and an approach that considers severe accidents in containment design by establishing practical design requirements based on calculations of stylized loads on the containment. The DSAC Development Project utilized a formal expert opinion process to provide a quantitative specification of the severity of the loads and a reviewable technical basis. The goals for the project were to (1) generate specific proposals for quantitative criteria within the specified project schedule; (2) minimize the phenomenological uncertainty residing in the problem statements and success criteria so that the design's compliance with the criteria would not be the subject of protracted contention; (3) follow a formal plan consisting of well-defined steps, each of which was scrutable and reviewable; (4) ensure that the complete spectrum of credible severe accident threats was covered by the criteria; and (5) avoid over-constraining the design. As a result of the output of this process, the DOE's Office of Heavy Water Reactor was able to integrate the project recommendations with numerous other inputs to promulgate design criteria that were conservative, but not excessively so, and that could be technically reviewed and defended.

Such a level depression can take place if the core steaming rate is almost balanced with the steam condensation rate in the reactor coolant system (RCS). Integral experiments simulating three steam condensation modes in the RCS have shown that quasi-static level depressions can happen and thus have the potential for causing a prolonged uncovery and heatup of the core upper regions.

This follow-on study, which will be provided in full in NUREG/CR-5404-V2, provides a closure to the Phase I Study. For each of the component types and for the various types of component failure identified in the Phase I Study, the methods of failure detection were designated and tabulated, and the following findings became evident: Instrumentation and control (I&C) related failures dominated the group of failures that were detected during demand conditions. Many of the potential failure sources not detectable by the current monitoring practices were related to the I&C portion of the system. Some component failure modes are actually aggravated by conventional test methods. Several important system functions did not undergo function verification test. The goal of this follow-on study was to categorize and evaluate the deficiencies in testing identified by Phase I and to make specific recommendations for corrective action. In addition, this study presents discussions of alternate, state-of-the-art test methods and provides a proposed AFW pump test at normal operating pressure, which should do much to verify system operability while eliminating degradation.

When an antiproton annihilates at rest on the surface of an actinide nucleus, such as uranium, many fragments and neutrons are also produced, following direct reaction, nuclear evaporation, and fission processes, along with production of high-energy gammas and pions. Collectively, these processes have been termed antiproton fission, for simplicity, because many neutrons are produced as the end result of all reactions. Recent experiments at CERN suggest that as many as 15 to 20 neutrons are emitted following antiproton annihilation on U-238, that their distribution is peaked near 5 MeV in energy, and that a sizeable fraction (45 to 75%) of the annihilation energy (1.88 GeV per annihilation) is deposited locally in the U-238. A fit to the experimental neutron spectrum of Angelopoulos et al. is presented, and the systematics of transporting and annihilating antiprotons in a multigroup representation are investigated for the first time. Applications of antiproton transport and fission in small spherical assemblies are discussed and contrasted, mainly systematics of local and nonlocal antiproton annihilation, criticality, and disassembly.

By partitioning the components of the light water reactor (LWR) spent fuel and by transmuting key elements, such as the plutonium, the minor actinides, and a few of the long-lived fission products, some of the most significant challenges in building a waste repository can be substantially reduced. The proposed machine, based on the described PHOENIX Concept, would transmute the minor actinides and the iodine produced by 75 LWRs and would generate usable electricity (beyond that required to run the large accelerator) of 850 MW (electric).

The technical advantages include, in addition to geologic waste isolation, geographical isolation, near-zero groundwater flow through the disposal site, and near-infinite ocean dilution as a backup in the event of a failure of the repository geological waste isolation system. The institutional advantages may include reduced siting problems and the potential of creating an international waste repository. Establishment of a repository accepting wastes from many countries would allow cost sharing, aid international nonproliferation goals, and ensure proper disposal of spent fuel from developing countries. Major uncertainties that are identified in this concept are the uncertainties in rock conditions at waste disposal depths, costs, and ill-defined institutional issues.

The finite difference model as developed necessarily includes treatment of mass transport in both the waste and surrounding medium and allows calculation of release rates for cases with and without preferential adsorption and differing diffusivities of the two media. The dimensionless contaminant release rate was found to vary over several orders of magnitude depending on the product of the ratio of the distribution coefficient and the media diffusivities only. As would be intuitively expected, partitioning favoring the surrounding medium and higher relative waste medium diffusivity cause higher transport rates. There was definitely no unexpected enhancement in the release rate in the case of perforations over that of an uncontained waste form.

New regulations and architectural designs are being developed for residential areas, homes and public buildings. Radon concentration is directly related to the ratio between energy conservation and open-window ventilation. A large percentage of the accumulated radon comes via its infiltration through walls and floors (Cohtern et al, 1987). Some possible solutions to the problem involve: 1) The use of thermally-insulated boards which still allow the passage of radon to the outside; and 2) the use of coatings to reduce the infiltration through the wall and floors.

Nuclear moments are extracted from the data and agree well with predictions from particle-triaxial rotor model assuming slight oblate deformation for both states. This deformation corresponds to the minima in the Total Routhian Surfaces obtained from Strutinsky type calculations, the deformation being larger for the 9/2 state as indicated also by the experimental isomer shift.

The observed spin polarization of Ti-43 showed a reversed tendency in its momentum dependence compared with that observed for fragments produced in the Ca-40 on Au collision. This suggests negative angle deflection of Ti-43 due to the nuclear attractive potential. From the observed NMR spectrum, the magnetic moment of Ti-43 was determined to be \mu\=(0.85 +/- 0.02) mu(N). The value is significantly quenched from the single particle value -1.91 mu(N), which shows a strong effect due to meson exchange currents and configuration mixing. C1 RIKEN,WAKO,SAITAMA 35101,JAPAN.

With our high statistics, gamma-gamma-gamma coincidences where the two gates are on transitions in the two partner Fragments were extracted. Comparing the Cf-252 and (242)pU data allowed unique placements of many transitions. New, higher spin states were observed in many nuclei, up to 16(+) in some of the heavy partners. Levels in several nuclei were observed for the first time. Studies of the fission process included measured relative branchings to the In to 6n channels. Much data remains to be analyzed. These data provide new insights into the changing structures at higher spins of many neutron-rich nuclei and the fission process. C1 IDAHO NATL ENGN LAB,IDAHO FALLS,ID 83415.

In the past several years the P factor has been used to correlate a variety of properties of nuclear ground states and structures at low excitation energy. Here we present two new applications of this simple scheme: the isotopic systematics of 2(1)(+) states and the linearization of intruder O+ states in the Pb region. The results show the versatility of the P-factor as a simple embodiment of the competition and balance between the p-n and pairing residual interactions that seem to determine much of the behavior of ground and excited configurations of medium and heavy nuclei.

The alpha decay of Pt-185 and Au-186 was observed for the first time and several new alpha groups were observed for the decay of Au-181-185. By simultaneous measurement of gamma-rays and x-rays and use of known ec/beta(+) decay schemes, alpha-decay branching ratios and hindrance factors were deduced for each alpha transition. Several previously unknown low-lying gamma-ray transitions were observed in the Ir daughters by means of alpha-gamma coincidence measurements. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

The distribution of the singular values has an important bearing on the convergence behavior of the conjugate gradient method applied to the normal equations. The eigenvalue distribution has an important bearing on various alternative conjugate gradient like iterative methods. The main results give a precise interval on which the singular values cluster. It is also shown that the (complex) eigenvalues cluster about an interval of the real axis under suitable assumptions. The analysis is based on the theory of collectively compact operators.

A fit to the nuclear-scattering distribution in the range 0.065 less-than-or-equal-to \t\ less-than-or-equal-to 0.21 (GeV/c)2 gives b = (16.2 t +/- 0.5 +/- 0.5) (GeV/c)-2 for the logarithmic slope parameter.

Multiple-stripe and broad-area lasers emit large output powers (4 and 5 W) and large efficiencies (39 and 50%) at currents of 4 and 7.2 x I(th). At high currents of 4 x I(th) multiple-stripe lasers emit beams containing multiple modes. These beams can have small consistent Opd divergences (1 3 deg) making it easy to couple into optical fibers for applications. Current increases in multiple-stripe lasers have little effect on their performance. Broad-area lasers can emit a single upsilon = 8 mode at currents up to 4.3 X I(th) but have large divergences (60 deg) making it difficult to couple into optical fibers. During burn-in, aging lasers can emit erratic optical beams. After aging, the output power and efficiency of a multiple-stripe laser decrease (3 and 6%), while that of a modified multiple-stripe laser increase (3.5 and 5%). Thermoelectric cooling instead of heat-fin cooling increases the output power and efficiency of a multiple-stripe laser (7.4 and 6%), and longer shot intervals increases the output power (5.4%). Modified multiple-stripe and broad-area lasers emit similar broad beams centered on their optical axes, and the beams get broader as current increases. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

The system includes a holographic grade Apollo ruby laser and a Cordin model 330A high-speed film camera. The laser has been modified to generate a train of 1 to 100 or more pulses having individual pulse energies of about 40 mJ and a pulse width under 50 ns. The separation between pulses is currently 8 mus, but is expected to soon be reduced to about 1 mus. The laser pulses are synchronized with the framing sync signals from the Cordin camera, so that an individual interferogram is recorded on each of the available frames (a maximum record length of 80 frames is possible). The system is currently configured as a diffraction moire interferometer that illuminates a specimen diffraction grating with a pair of laser beams. The resulting interferograms are recorded using the Cordin camera. The system and the experimental synchronization method are described and some representative experimental data are presented.

Insoluble impurities that segregate to the interface tend to suppress surface diffusion by chemically combining with the surface atoms, as in the creation of a metal oxide layer, or by simply presenting a physical barrier to the kinetic jump process. We propose a mechanism by which surface self-diffusion (and hence gas bubble diffusion) may in fact be enhanced during high-temperature anneals, for a special class of matrix-impurity couple. A liquid layer at the gas-solid interface, comprised of the impurity species and an equilibrium concentration of matrix atoms, acts as a conduit for rapid mass transport, as equilibrium is maintained by continuous dissolution and precipitation of matrix atoms at the solid surface. This liquid dissolution diffusion process thus requires that the impurity species melt at a temperature lower than the annealing temperature, that the liquid lower the gas solid interface energy and so wet the solid surface, and that the matrix species be soluble in the liquid impurity. Recent in situ observations by transmission electron microscopy of dramatically enhanced diffusive motion of helium bubbles in aluminium alloyed with lead and with indium may be evidence for this diffusion mechanism.

The analysis of the pre-peak at the absorption edge revealed that there exist both oxygen-deficient (100 angstrom or less wide) and fully oxygenated grain boundaries. These differences depend on the structural misorientations between grains separated by boundaries. The results were consistent with earlier predictions of variable oxygen contents at YBa2Cu3O7 grain boundaries, depending on the misorientations, based on the constrained coincident-site lattice model for the boundary structures.

As the thermochemical reduction takes place at increasing temperature, a dark colouration emerges at the strained region. The colouration at the strained region is always darker than the surrounding unstrained region, regardless of the temperature of reduction. Optical absorption measurements reveal that the colouration is due to a very broad band peaking at about 800 nm. There is no evidence from transmission electron microscopy and X-ray microanalysis to indicate the presence of precipitates in as-grown and thermochemically reduced crystals, in contrast with oxides in which cation impurities tend to form metallic precipitates preferentially at strained regions during thermochemical reduction.

Based on literature reports and on an energy conservation potential, research on the potential of using biosolubilization for the industrial processing of rock phosphate ores appears to be worth while. This paper reports on efforts to develop such a process. Activities related to the isolation and selection of phosphate solubilizing microbial species as well as those efforts to develop a bench top bioprocess unit for the continuous solubilization of phosphate ore are discussed.

The zero-phonon hole (ZPH) widths for B800 at 4.2 K are 6.0 +/- 0.3 cm-1 and are discussed in terms of B800-B850 and B800-B800 energy transfer. The B800* lifetime is 1.8 +/- 0.2 ps. The site inhomogeneous broadening (GAMMA(I)) of B800 is 240 cm-1. The B850 (located at 864 nm at 4.2 K) hole spectra reveal that B850 suffers from significant homogeneous broadening, which is attributed to unit cell exciton level structure and ultrafast interexciton level relaxation. Novel ZPH action spectra lead to the resolution of a minor component at 885 nm, which is the analogue of B870 of Rhodobacter sphaeroides previously assigned as the lowest exciton level of the B850 exciton band. The B870 ZPH width of 2.0 +/- 0.2 cm-1 for Rhodopseudomonas acidophila leads to a total dephasing time of 5.3 ps, which is attributed to exciton scattering that stems from the energetic inequivalence of neighboring B850 unit cells.

We describe here instrumentation and computational methods for acquiring and analyzing the resonant ultrasound spectrum of very small (0.001 cm3) samples as a function of temperature, and provide examples to demonstrate the power of the technique. The information acquired is in some cases comparable to that obtained from other more conventional ultrasonic measurement techniques, but one unique feature of resonant ultrasound spectroscopy (RUS) is that all moduli are determined simultaneously to very high accuracy. Thus in circumstances where high relative or absolute accuracy is required for very small crystalline or other anisotropic samples RUS can provide unique information. RUS is also sensitive to the fundamental symmetry of the object under test so that certain symmetry breaking effects are uniquely observable, and because transducers require neither couplant nor a flat surface, broken fragments of a material can be quickly screened for phase transitions and other temperature-dependent responses.

In particular, calculations show that the gain of the anomalously weak J = 0 --> 1 laser line is inversely proportional to the 3p --> 3d collisional mixing rate while the J = 2 --> 1 laser lines are virtually unaffected by changes in this collision rate. Potential resonances between DELTAn = 0 transitions are discussed which may explain the unusual output of Ne-like Y as compared to other nearby Ne-like lasers.

These spectrometers have a very high spectral resolution, lambda/DELTAlambda > 10 000, and are mainly used to determine the central ion temperature from Doppler broadening measurements of the 1s-2p resonance lines of high-Z helium-like ions. The full diagnostic potential of the spectra of helium-like ions is demonstrated by the detailed analysis of Fe XXV satellite spectra from a particular high temperature tokamak discharge with reactor-like conditions. This analysis is based on least squares fit comparisons of the experimental data with synthetic spectra, which are constructed from theoretical predictions. It is found that the satellite spectra which are associated with the helium-like resonance lines are in excellent agreement with the theoretical predictions. The satellite spectra can therefore be used for electron temperature measurements, measurements of the dielectronic recombination rate coefficients and the determination of relative ion charge-state abundances. Discrepancies between experiment and theory are, however, observed for the intensity ratios of the helium-like lines. Also discussed are atomic physics data needs and the potential of the X-ray diagnostic for future large tokamaks, such as ITER.

In contrast to previous lifetime measurements of these two 5p states, this work used both state-specific excitation and low pressures. The pressures were low enough that collisional transfer between these two states was negligible. In a very clean 8-mm-diam cell, the 5p[5/2] J = 3 lifetime increased with Kr pressure. This increase is attributed to radiation trapping on the 5s[3/2] J = 2 to 5p[5/2] J = 3 transition. This radiation trapping by the metastable first excited state of Kr I was observed in a pure Kr discharge at pressures below 4 mTorr.

State-selective preparation of 6s6p P-1(1,mj) and detection of 6s6p P-3(2,mj') was achieved using the laser excitation technique in the presence of a magnetic field that breaks the degeneracy of the magnetic sublevels. The results showed that the Zeeman cross sections sigma(P-1(1,mj) --> P-3(2,mj')) are fairly dependent upon m(j) and m(j)' for N2 and H-2, whereas the Zeeman cross sections all have the same value with O2. Additionally the flux-velocity contour map of Ba(6S6p P-3(2)) for scattering with H-2 depends significantly upon the magnetic sublevel of barium in the exit channel. The results for Ba-(N2, H-2) scattering were accounted for semi-quantitatively by a very simple model. The model was then used to stress which physical phenomena are at the origin of the preservation of the orbital alignment and orientation during collisions. The present work also compared the kind of information obtained by the direct measurement of Zeeman cross sections to that found in other experiments that deal with the effect of polarizing the collision partners.

Besides dominant transitions to core-excited inner-well states, several series of Rydberg states with vibrational fine structure were resolved below the sulfur L 2,3 thresholds. Using the Rydberg formula, quantum defects of delta(s) = 1.80 and delta(d) = -0.03 were obtained for the s and d Rydberg orbitals of the central sulfur atom. A Franck-Condon analysis was used to determine the vibrational spacing and the S-F bond length of the (S 2p3/2)(-1)4s1 core-excited state. The presence of vibronically coupled transitions below the sulfur L2,3 edges was confirmed. The derived natural linewidths of the (S 2P1/2,3/2)-1 Rydberg states were found to be strikingly narrower than those of the (S 2p1/2,3/2)-1 inner-well resonances. Line-shape analysis also revealed significant inhomogeneous broadening of the (S 2p1/2,3/2)-1a1g1 states, which is attributed to unresolved vibrational structure. Large Lorentzian contributions to the line shapes of the (S 2P1/2,3/2)-1t2g1, resonances suggest that vibrational effects are relatively small for those states.

The spectra were emitted from high-density laser-produced plasmas. Plasmas were produced by irradiating thin- and thick-foil targets made of magnesium, aluminum, phosphorus, and chlorine with the OMEGA laser in a line-focus geometry. Line profiles were compared to a Stark-broadening calculation that uses the static-ion approximation and an impact approximation for the electrons. The dependence of Stark broadening on atomic number is discussed. For the aluminum plasmas approximately 10% narrowing was observed in the width of the 3d-5f line as the length of the plasma was increased from 3 to 6 mm.

The valence-band spectra of both alloys do not change significantly with photon energy and their structure is essentially identical. The feature at 0.7 eV below the Fermi level is shown, by employing resonant photoemission near the Fe 3p threshold, to be due mainly to Fe 3d states, and the feature at 4.0 eV originates primarily from Cu 3d states. No unusual features in the valence band of the icosahedral Al65Cu20Fe15 alloy, which could be associated with its quasicrystalline nature, are observed within the energy resolution of the experiment. A rapid decrease of the intensity towards the Fermi level is interpreted to be indicative of the existence of a minimum in the density of states at the Fermi level. It is argued that the similar electronic structure of the alloys supports a recently proposed structural model of icosahedral Al65Cu20Fe15. A review of published experimental data on the electronic structure of quasicrystals and a survey of various theoretical analyses are also presented.

The atoms are spread randomly in a periodically repeated cell and then relaxed using Weber-Stillinger pair potentials to a local minimum potential energy. We have constructed eight such cells for each concentration. Because the unit cell (80 or 160 atoms) is larger than the electronic mean free path, we can assume the electronic properties are independent of boundary conditions. We impose periodic boundary conditions, which is equivalent to calculating the band structure at k = 0 of the periodically extended unit cell. Using linearized Korringa-Kohn-Rostoker (KKR) band theory, we have calculated the total density of states, component- and angular-momentum-decomposed densities of states, degree of localization, and current matrix elements for the electrons. We find very little localization of the electrons near the Fermi energy. We also have calculated the electrical resistivity and reflectivity as a function of frequency and concentration using the Kubo formula. Finally we have compared our calculated results with experiment and with results obtained from the effective-medium approximation and from the KKR coherent-potential approximation.

The observed shifts of the soft-x-ray emission spectra relative to the photoelectron spectra are identified as Stokes shifts and are described in terms of partial phonon relaxation. The observed Stokes shifts are 0.5, 0.9, and 1.2 eV for MgO, Al2O3, and SiO2, respectively. Similar measurements on Mg, Al, and Si show no detectable Stokes shift within the experimental uncertainty of 0.2 eV. The larger Stokes shifts observed in the oxides are due to the longer core-hole lifetime, the faster phonon relaxation, and larger phonon relaxation energy in the oxides.

The small moment found on the interfacial Cr atoms is aligned antiparallel for 3 Fe layers and parallel for monolayer Fe to the nearest-neighbor Fe moments in the Fe(m)/Cr(n) (001) superlattices, respectively. For the former case the ferromagnetic alignment for the two consecutive Fe layers separated by Cr layers dominates over the antiferromagnetic alignment, whereas a crossover is seen when the number of Cr layers is increased to 5 (or perhaps 3) layers in between a single Fe layer, i.e., a (slightly) lower total energy for the antiferromagnetic state with respect to the ferromagnetic state.

The films were epitaxially deposited onto polished (100) MgO substrates and covered by protective layers of gold. The results show that at 40 K all films are ferromagnetic, with an average magnetic moment per iron equal to 2.2+/-0.2mu(B) regardless of film thickness. However, the thinnest films exhibit a Curie temperature lower than that of the bulk and a magnetization axis tilted out of the film surface. These results are discussed in the light of the detailed morphology of the films, and compared with the theoretical predictions.

Rev. B 45, 13 125 (1992)]. To show an instability in the odd gap channel, a model phonon propagator was used with the p-wave interaction strength larger than the s-wave strength. We argue that the positive scattering matrix element entering the Eliashberg equations leads to a constraint on the relative strength of p- and s-wave interactions, which inhibits odd pairing. However, a general spin-dependent electron-electron interaction can satisfy all constraints and produce the odd singlet gap. A possibility that may lead to an odd gap is a strongly antiferromagnetically correlated system, such as a high-T(c) material. C1 LOS ALAMOS NATL LAB,DIV THEORY,LOS ALAMOS,NM 87545.

Two systems-a monolayer (1Ni/Fe) and a bilayer (2Ni/Fe) coverage on Fe(001)-are investigated and compared. The Ni-Fe interlayer spacings are found to be relaxed downward by 2.5% and 4% for 1Ni/Fe and 2Ni/Fe, respectively. The effect of the Ni-Fe hybridization on the electronic and magnetic properties is examined. In both overlayer systems the magnetic moments at the interface Ni and Fe sites are enhanced relative to their corresponding bulk values. The magnetic moment (0.69mu(B)) of the surface Ni atom of 2Ni/Fe is found to be reduced from that (0.86mu(B)) of the surface Ni atom on 1Ni/Fe. A manifestation of the moment enhancement at the interface Fe site is a positive contribution to the hyperfine field from the valence electrons.

The uranium moments have previously been shown to exhibit two antiferromagnetic phase transitions at approximately 25 and 40 K. The c axis is known to be the hard magnetic axis, and if the field is applied in the hexagonal basal plane, the magnetization measurements show a low-temperature spin-flop transition at approximately 3 T. In the present measurements, the field was applied along the [100] direction of the orthorhombic magnetic unit-cell. We have studied the temperature dependence of the (010) antiferromagnetic reflection, which corresponds to the order parameter of the 25-K transition, at fixed fields; the ground state is stable for fields below 3.5 T and temperatures below 25 K, and we have established the magnetic phase boundaries in this regime. We also made a series of measurements in which the sample was zero-field cooled from high temperature and then the field was ramped up and down at fixed temperature. In this configuration, we observe significant irreversible domain repopulation effects below the spin-flop transition as the field is increased, but the curves obtained on reducing the field from above the spin-flop transition seem to be indicative of intrinsic single-domain properties; they are consistent with the field-cooled data. We have also studied the induced (ferromagnetic) moment, and have found that the behavior is very different above and below the 25-K transition. For T < 25 K, there is a sharp transition at approximately 3 T in agreement with bulk magnetization measurements, while above 25 K, the magnetic intensity rises parabolically with fields as would be expected for a simple antiferromagnet; the induced magnetic moment in this case arises from the transverse magnetic susceptibility.

The end-member compound, BaBiO3, has a half-filled electronic band, and a charge-density-wave (CDW) ground state, while at x congruent-to 0.4 this material is a superconductor with T(c) congruent-to 30 K. Excitations across the CDW energy gap produce a large peak in the optical conductivity at about 16000 cm-1 (2 eV), which shifts to lower energy and broadens as the band filling is reduced by doping (x > 0). For compositions near x = 0.4 a broad contribution to the conductivity extending from congruent-to 3000 cm-1 to 10000 cm-1, which appears to have evolved from the CDW peak, is still observed. These observations suggest that a remnant CDW-like order may still be present even in the composition range where superconductivity occurs. They also highlight fundamental differences in the electronic properties of bismuthate and cuprate materials. C1 ARGONNE NATL LAB,DIV MAT SCI,ARGONNE,IL 60439.

The I L1-edge results indicate that the intercalated iodine layers receive electronic charges and the I 5p-orbital holes are in states primarily oriented in the I plane. The Cu K-edge results show that the electronic structure of the CuO2 layer is only slightly affected by the iodine intercalation. Some evidence for a small shift of the unoccupied Cu bands towards higher energy and a weakening of the ligand to Cu charge transfer is seen. These effects could nevertheless be contributing factors to the decrease of T(c). It is observed that iodine intercalation induces about 0.25 eV downward (and upward) edge shift in the Bi L3-edge spectrum with the polarization vector E parallel-to c axis (and E perpendicular-to c axis). We interpret this observation by the downward shift of the out-of-plane part and upward shift of the in-plane part of the 6d(t)2g and 6d(e)g states, caused by the change of the Bi-O bonding configuration from octahedral to pyramidal. Our results indicate that the Bi valence state is close to +3 in both IBi2Sr2CaCu2Oy and Bi2Sr2CaCu2Oy crystals but with the Bi sites manifesting a more metalliclike behavior along the c-axis direction upon iodine intercalation.

The spin magnetic moment as a function of strain has a rather complicated structure including two well-defined cusps and an abrupt collapse from a high-spin state to a low-spin state. These features are shown to be directly related to a confluence of critical points in the electronic band structure with the Fermi level. On the basis of these results, a test for modern approximations to spin-dependent density-functional theory is proposed.

The uncertainty in the absolute normalization (based on the simultaneously measured yield of deuterons from the np --> dpi0 reaction) was initially estimated to be approximately 7%. The results agree well with back-angle data obtained independently at LAMPF but less well with results from Saclay and the Princeton-Pennsylvania Accelerator and, except for a normalization difference of 10%, are fairly well represented by a phase-shift fit. The pole-extrapolation method of Chew was used to extract the pion-nucleon coupling constant f2 from the back-angle portion of the data. The value obtained, f2=0.069, is somewhat smaller than the values 0.0735-0.0790 obtained from analyses of pion-nucleon scattering, tending to confirm the need for an upward renormalization of the angular distribution by approximately 10%.

The beta decay of 194Bi, with its large Q(beta) value and high spins of the decaying isomeric states, provides a favorable opportunity to search for population of known SD states in the daughter nucleus, 194Pb. Both gamma rays and conversion electrons were measured in singles and coincidence; however, no evidence for the population of SD states was observed. Upper limits for the population of certain SD states are presented. A possible explanation for the lack of SD band population following this beta decay is discussed.

The difference in ground-state (t,alpha) Q values for Hf-178 and Hf-179 components of the target, combined with the known masses of Lu-177, Hf-178, and Hf-179, yields an improved value of -50351 +/- 5 keV for the mass excess of Lu-178. This result, combined with the two-quasiparticle assignments from the present work, has resolved the long-standing puzzle concerning the character and excitation energy of the well-known 23 min high-spin beta-decaying isomer in Lu-178.

Experimental data on half-lives, Q values, and branching ratios are tabulated. Experimental logft values and beta-decay matrix elements are deduced from these data. The one-body-transition densities necessary to predict the beta-decay matrix elements are then calculated using a recently constructed shell-model Hamiltonian operating in the first four major shells. Using these parameters, effective Gamow-Teller operators are deduced for the Op shell from a least-squares fit to 16 experimental matrix elements. The effective operators are used to calculate 83 decay matrix elements. Some specific decays are discussed. C1 CLARK UNIV,WORCESTER,MA 01610. NATL SUPERCONDUCTING CYCLOTRON LAB,E LANSING,MI 48824.

Neutrons are produced by spallation of the 800 MeV proton beam from the Los Alamos Meson Physics Facility accelerator incident on a thick, heavily shielded tungsten target at the Weapons Neutron Research facility at Los Alamos National Laboratory. Transmission measurements were completed for fifteen elements with 9 less-than-or-equal-to A less-than-or-equal-to 209 and three isotopically enriched samples of Ca-40, Zr-90, and Pb-208. Principal features of the experiment are the intensity and time structure of the neutron source, tight collimation of the neutron beam line, good geometry, rapid cycling of the samples, stable electronics, and a small, fast neutron detector. Errors due to counting statistics were generally less than 1 % for each of several hundred energy bins for each target. The measurements represent steps in the development of a neutron-nucleus optical potential at intermediate energy and important input for the clarification of isovector effects in the nucleon-nucleus interaction. The data also provide insight into the long-standing discussion of mean free paths of the nucleon in the nucleus. C1 LOS ALAMOS NATL LAB,P DIV,LOS ALAMOS,NM 87545.

The measurements were made from reaction threshold to 17 MeV with the Lawrence Livermore National Laboratory's Tandem Van de Graaff accelerator using the stacked-foil method. The Br-79(d,2n)Kr-79 and the Br-81 excitation functions are the first reported. The targets consisted of the halides dispersed in the plastic Kapton. The activated targets were assayed using gamma counting and mass spectrometry. We found that we had to remeasure the gamma intensities for the Kr-79 decay. The excitation functions were modeled using the Hauser-Feshbach statistical-model code STAPRE, using the exciton preequilibrium model. We found a preference for the back-shifted (BS) level density prescription over the use of the Gilbert-Cameron prescription. For BS, the constant K, governing the transition to equilibrium, was taken as 500 to 700 MeV3. These values gave preequilibrium fractions consistent with those we obtained from ion-recoil range studies of light ion reactions. In general the modeling agreed well with experiment. For the deuteron induced reactions, we had to allow for deuteron breakup using a microscopic breakup fusion approach developed by Udagawa and Tamura. Our analysis of the stripping reaction, Br-81(dp)Br-82, by this procedure is especially noteworthy.

The data are compared with calculations which account for the reaction dynamics in terms of an intranuclear cascade, followed by statistical decay of the excited residues. General agreement between the data and calculations is found for the spectral shapes and mass distributions; however, the experimental angular distributions are significantly more forward peaked than predicted. This suggests a failure of the model to account satisfactorily for momentum transfer in the collision stage. These results extend linear momentum systematics for He-4 projectiles near the Fermi velocity to significantly lower target mass than previously measured. Implications of the data to questions of cosmic ray astrophysics and radiation damage in microelectronic circuits are also discussed. C1 INDIANA UNIV,IUCF,BLOOMINGTON,IN 47405.

The model considers rotational excitation due to the Coulomb field in the entrance channel, neutron transfer between the two nuclear surfaces at the distance of closest approach, and additional rotational excitation in the final channel. The Coulomb excitation processes are described within the sudden-limit approximation using classical-limit theory, and the transfer is described in terms of spectroscopic amplitudes obtained with the particle-rotor model. We have applied this model of transfer to the Ni-58 + Dy-161 and Sn-116 + Dy-161 one-neutron pickup reactions, cases for which data are available. The calculations indicate that transfer into both ground and two-quasiparticle excited bands takes place and that the distribution of population in the ground band and two-quasiparticle states is in reasonable agreement with the data.

An investigation of capture of 2 and 24 keV neutrons in a Gd-156 target resulted in resonance-averaged intensities of primary gamma rays between 3.7 and 6.4 MeV. From these intensities the gamma-ray strength functions have been derived for El and M1 radiation. We compare several formulations of strength functions to these resonance capture and/or photoabsorption data. Further we use these prescriptions in calculations of the total average radiation width, radiative capture cross sections, and gamma-ray spectra, and compare them to available experimental information. By analyzing these results strong evidence was found for an El strength function which is based on a generalized Lorentzian, enhanced compared to spherical nuclei, with an energy-dependent spreading width and a nonzero limit as the energy tends to zero. For M1 radiation the giant resonance spin-flip mode is favored. C1 UNIV VIENNA,INST RADIUMFORSCH & KERNPHYS,A-1010 VIENNA,AUSTRIA. BROOKHAVEN NATL LAB,UPTON,NY 11973.

The calculation of the first-order potential includes (1) full Fermi-averaging integration including the DELTA propagation and the intrinsic nonlocalities in the pi-N amplitude, (2) covariant kinematics, (3) invariant amplitudes, and (4) a finite-range off-shell pion-nucleon model which contains the nucleon-pole term. The DELTA nucleus interaction is included via the mean spectral-energy approximation. This approach produces a convergent perturbation theory in which the Pauli corrections (treated as a second-order term) cancel remarkably against the pion true-absorption terms. Parameter-free results, including the DELTA-nucleus shell-model potential, Pauli corrections, pion true absorption, and short-range correlations, are presented.

The measured nu(e)e- --> nu(e)e- elastic scattering rate of 236 +/- 35 events yields the total elastic scattering cross section 10.0 +/- 1.5(stat) +/- 0.9(syst) x 10(-45) cm2 x [E(nu) (MeV)], and a model-independent measurement of the strength of the destructive interference between the charged and neutral currents, I = -1.07 +/- 0.21, that agrees well with the standard model (SM) prediction I = -1.08. The agreement between the measured electroweak parameters and SM expectations is used to place limits on neutrino properties, such as neutrino flavor-changing neutral currents and neutrino electromagnetic moments. Limits are placed on the masses of new bosons that interact with leptons: for a neutral tensor boson, M(T) > 105 GeV; for a neutral (pseudo)scalar boson, M(P,S) > 47 GeV; for a charged Higgs boson, M(x+) > 87 GeV; and for a purely left-handed charged (neutral) vector boson, M(x) > 239 (119) GeV.

Within the context of the nonrelativistic quark model, we introduce the running toponium width GAMMA(THETA)(E,p) in the Schrodinger equation for the three-point Green's function that governs the ttBAR contribution to the e+e- annihilation process. The effect of the running of the width is found to be significant in two aspects: (i) it takes account of the phase-space volume for the decay process ttBAR --> bW+bW-BAR and provides a consistent framework for calculating the differential cross sections; and (ii) it reduces the widths of the low-lying resonances to considerably less than 2GAMMA(t)(m(t)2). Furthermore, the running of the width causes the total cross section to decrease significantly at c.m. energies below the first ''resonance'' enhancement, whereas it makes the ''peak'' cross section more distinct than is obtained in the fixed toponium width approximation. We use the two-loop-improved QCD potential in our calculation, and the alpha(s)(m(Z))MSBAR dependences of the total and differential cross sections are studied quantitatively, where MS denotes the modified minimal subtraction scheme. We find that the correlations in the alpha(s) and m(t) measurements are opposite in the total and differential cross sections, and the simultaneous measurements would lead to an accurate determination of both parameters.

This observation, due to Dokshitzer, Khoze, and Troyan. is studied to see whether it serves as a signature for detection of the Higgs bosons, etc. We find it is a very strong signature at subprocess c.m. energies in excess of a few TeV. The most serious problem with this strategy is the estimation of the fraction of events containing the rapidity gap; most of the time the gap is filled by soft interactions of spectator degrees of freedom. We also study this question and estimate this ''survival probability of the rapidity gap'' to be of order 5%, with an uncertainty of a factor 3. Ways of testing this estimate and further discussion of the underlying bard-diffraction physics are presented.

We perform a one-loop Feynman diagram calculation in the on-mass-shell renormalization scheme, and include the third generation of quarks and squarks. The tree-level rate is suppressed by a mixing angle factor and decreases as 1/M(H) for large M(H). The corrected rate overcomes this suppression and increases with M(H) for M(H) sufficiently large. The corrections can be very large and depend in detail on the top-squark masses and A term, as well as the supersymmetric Higgs-boson mass parameter mu. C1 LAWRENCE BERKELEY LAB,BERKELEY,CA 94720.

In particular, we study scenarios where the 17-keV neutrino is a pseudo Dirac neutrino and its mass is generated radiatively. Two heavy right-handed neutrinos have their mass scale set by the SU(2)R-breaking scale, and the two light-neutrino masses are then determined by a seesaw mechanism. This scenario requires new Higgs bosons beyond those necessary in a minimal left-right model. The left-right symmetry leads to relations between the charged- and neutral-lepton mass matrices. We examine the constraints on the model from charged-lepton masses, leptonic flavor-changing neutral currents, neutrino data, cosmology, and astrophysics.

The spectroscopy of these systems is essentially identical. Parametrizations of the wave functions are presented which can be used as interpolating fields for spectroscopy calculations. The sizes of particles are calculated using these parametrized wave functions. The resulting sizes are small, approximately half the sizes of the physical states. The charge radius of the neutron, which provides an indication of the asymmetries between the wave functions of up and down quarks, is calculated. Although the size of the nucleon in these simulations is small, the ratio of the charge radius of the neutron to that of the proton is consistent with the physical value. We find no significant differences between the quenched and dynamical simulations. C1 FLORIDA STATE UNIV,SUPERCOMP COMP RES INST,TALLAHASSEE,FL 32306. UNIV COLORADO,BOULDER,CO 80309.

We show that a model-independent direct summation method allows accurate numerical evaluation of all known classes of these (in)finite continued fractions that arise in dynamics problems and thus provides a powerful technique to study the dynamics of many-body and few-body systems. Some studies on dynamical correlations in s = 1/2 quantum spin chains are cited as applications of the method presented. C1 BROOKHAVEN NATL LAB,DIV MAT SCI,UPTON,NY 11973.

We apply our result to the classical case of two semi-infinite fluids with densities rho1 and rho2 and viscosities mu1 and mu2. Treating a shock as an instantaneous acceleration we find that perturbations at the interface undergo damped oscillations when viscosity and surface tension are both present. For pure viscosity the amplitude eta(t) evolves according to eta(t)/eta(0) = 1 + (DELTAupsilon A/2knu)(1-e-2k2nut) where DELTAupsilon is the jump velocity imparted by the shock, A=(rho2-rho1)/(rho2+rho1), nu=(mu1+mu2)/(rho1+rho2), k=2pi/lambda is the wave number of the perturbation, and t is time. We also consider the turbulent energy in accelerating fluids and calculate the reduction in E(turbulent) as a function of nu, and propose experiments to measure the effect of viscosity on RT and RM instabilities.

We find that fluctuations in the shock location, about an average determined by evolving an ensemble of systems with the same initial conditions, generically grow in time like t1/3. We discuss the robustness of the t1/3 growth and determine the density dependence of the coefficient in a simple case. We compare this with models where the dynamics are specially tuned so that the growth is reduced to t1/4, and with the situation where the ensemble members have different initial conditions, in which case the growth is like t1/2.

The model uses the stretching of the hydrogen bonds in a base pair as its main variable. Numerical simulations at constrained temperature show that it provides a good qualitative description of the collective motions of the base pairs, including their large-amplitude fluctuational openings and the emergence of the denaturation bubbles from the thermal fluctuations. The results are in good agreement with a statistical-mechanics analysis of the denaturation and specific-heat curves, performed with the transfer-integral method, provided that discreteness effects are treated exactly by a numerical solution of the transfer-integral operator. Second-order self-consistent phonon theory agrees with the exact transfer-integral results in the low- and intermediate-temperature ranges and explains the phonon softening observed in the molecular-dynamics simulations. When the temperature approaches the denaturation temperature, the second-order self-consistent phonon results deviate significantly from the exact ones, pointing to the fundamental role of nonlinear processes in DNA denaturation.

Rev. Lett. 66, 1123 (1991)]. Using different fixed points, we find that the solutions in a chaotic regime can also be periodic. Since the laser equations are isomorphic to the Lorenz equations we use this method to control chaos when the laser is operated over the pump threshold. Furthermore, by solving the laser equations with an occasional proportional feedback mechanism, we recover the essential laser controlling features experimentally discovered by Roy, Murphy, Jr., Maier, Gills, and Hunt [Phys.

Tadic, U. Nowak, K. D. Usadel, R. Ramaswamy, and S. Padlewski, Phys. Rev. A 45, 8536 (1992)], the directed two-dimensional sandpile is modified to include a concentration p of randomly placed holes. For p>0, they observe a characteristic cutoff size for the duration (and mass) of avalanches. This breaks the formal power-law behavior that is a signature of self-organized criticality. The scaling of these characteristic sizes with the concentration of defects is observed empirically to follow a power law, and the exponents are numerically determined. In this Brief Report, it is shown that a previously described mean-field approximation can account for the observed exponents. C1 LOS ALAMOS NATL LAB,DIV THEORET,LOS ALAMOS,NM 87545.

Using an integral approach and lubrication approximation, transport equations governing the spatiotemporal evolution of a film thickness and the temperature along the film are obtained. Evolution of the system under both isothermal and nonisothermal conditions is studied numerically. It is shown that nonlinear interaction of the linearly unstable modes begets an additional mode with a wavelength equal to that of the fastest growing wave. This, in turn, causes the formation of satellite drops along with the main ones. Application of these results in a possible continuous technology of high-temperature superconductor wire fabrication is discussed. C1 LOS ALAMOS NATL LAB,CTR NONLINEAR STUDIES,LOS ALAMOS,NM 87545.

These two-dimensional equilibria are also called rotating coherent structures, and are stationary (time independent) in a frame of reference rotating with angular velocity omega(r)=const about the cylinder axis (r=0). Radial confinement of the pure electron plasma is provided by a uniform axial magnetic field B0e(z), and a grounded, perfectly conducting, cylindrical wall is located at radius r=r(w). The analysis is based on a nonrelativistic, guiding-center model in the cold-fluid limit (the continuity and Poisson equations) that treats the electrons as a massless fluid (m(e) --> 0) with E X B flow velocity V(e)=-(c/B0) delphi X e(z). Within this model, general rotating equilibria with electron density n(e)=nR(r,theta-omega(r)t) and electrostatic potentia] phi=phi(R)(r,theta-omega(r)t) have the property that the electron density is functionally related to the streamfunction psi(R)=-ephi(R) + omega(r)(eB0/2c) rw2 by n(R)=n(R)(psi(R)) The streamfunction psi(R) satisfies the nonlinear equilibrium equation del2psi(R)=-4pie2n(R)(psi(R))+2omega(r)eB0/c with psi(R)=w(r)(eB0/2c)r(w)2=-psi(w)=const on the cylindrical wall at r=r(w). Following a general discussion of rotating equilibria, an integral equation formulation of the nonlinear equilibrium equation is developed to investigate equilibria with ''waterbag'' (step-function) density profiles. In this investigation, a numerical method is formulated that can be used to construct diverse classes of highly nonlinear waterbag equilibria. This method is employed to investigate two classes of nonaxisymmetric equilibria that are nonlinear extrapolations of well-known small-amplitude equilibria. These two classes of rotating equilibria bear strong similarities to coherent structures observed experimentally by Driscoll and Fine [Phys. Fluids B 2, 1359 (1990)].

This low-noise nonlinear characteristic method for particle simulation is an extension of the partially linear weighting scheme, and may be considered an improvement over existing deltaf methods. Some of the features of this new method include the ability to keep all nonlinearities, particularly those associated with the velocity space, the use of conventional particle loading techniques, and also the retention of the conservation properties of the original gyrokinetic system in the numerically converged limit. The new method is used to study a one-dimensional drift wave model that isolates the parallel velocity nonlinearity. A mode coupling calculation for the saturation amplitude is given, which is in good agreement with the simulation results. Finally, the method is extended to the electromagnetic gyrokinetic equations in general geometry. RP PARKER, SE (reprint author), PRINCETON UNIV,PRINCETON PLASMA PHYS LAB,PRINCETON,NJ 08543, USA.

However, J1 can be quite large, going to infinity as the diode voltage approaches the limiting voltage V1 from below. Thus, it may not always be practical to inject a beam of current density exceeding J1. The results presented in this paper can be used to determine the fraction of (typically unwanted) ions extracted from the anode foil when J
