Use of gamma ray strength functions for predicting the neutron capture cross section of /sup 88/Y
The present study indicates that the estimation of the gamma-ray strength function is the approach least subject to error when unmeasured capture cross sections are to be computed. An estimate is given for the /sup 88/..gamma..(n,..gamma..) cross section.

Calculated neutron capture cross sections for the ground states and isomers of /sup 93/ /sup 94/ and /sup 95/Nb. [Resolved resonance region to 4 MeV, strength functions, statistical model]
Neutron-induced capture cross sections for the ground states and first isomeric states of /sup 93/Nb, /sup 94/Nb and /sup 95/Nb were studied from the resolved resonance region to 4 MeV via statistical model calculations. The production of isomers was included. Inelastic scattering cross sections and gamma-ray production spectra were also calculated. The anti GAMMA/ sub ..gamma..//D ratios were derived from gamma-ray strength function systematics. Total capture cross sections on the ground states are found to be within a factor of two of each other. Capture cross sections on the isomeric targets are important as well, not only because of their magnitude but also because of the significant population of these isomeric levels by inelastic scattering. 10 references.

Capture cross section and gamma-ray spectrum calculations for medium-weight nuclei. [Double-peak, energy-dependent Breit-Wigner model]
A double-peak, energy-dependent Breit-Wigner model of the E1 gamma-ray strength function was applied to nuclei from As to Rh, to predict their neutron capture cross sections and capture gamma-ray spectra. A consistent set of model parameters was obtained in this mass region to describe the step in the low-energy tail of the E1 strength function. This step allows agreement with photonuclear data at high energies, the correct GAMMA/sub gamma/ to be obtained for agreement with neutron capture cross-section data, and the calculation of the observed hardness in the capture gamma-ray spectra. For nuclei at or near the closed, N = 50 shell, however, the double-peak assumption breaks down. In these cases, good results are still obtained if the same set of model parameters is applied, except that the E1 strength function is formulated in terms of the first, narrower peak. 8 figures.

ORNL 150 keV neutral beam test facility
The 150 keV neutral beam test facility provides for the testing and development of neutral beam injectors and beam systems of the class that will be needed for the Tokamak Fusion Test Reactor (TFTR) and The Next Step (TNS). The test facility can simulate a complete beam line injection system and can provide a wide range of experimental operating conditions. Herein is offered a general description of the facility's capabilities and a discussion of present system performance.

Pulsed laser stereo photography of electrically exploded bridges
A technique is described for obtaining short exposure (approximately 8 ns) high resolution photomicrographs of electrically exploded bridges using a pulsed laser for bridge illumination and band-pass filters to eliminate the intense self light. Two cameras are described, one for a small field of view (approximately 1 mm) and one for a relatively large field of view (approximately 20 mm). A carbon disulfide cell and a fiber-optic light guide are used to essentially eliminate speckle, which normally limits the resolution of laser photographs of diffuse surfaces. A series of photomicrographs showing the detailed burst characteristics of both flat and round bridges are shown.

Studies of Charged Particle Distributions in an Electrostatic Confinement System. Progress Report, 1 November 1971--31 January 1976
Microwave cavity techniques were used to measure electron density in a spherical, inertial-electrostatic confinement device using six ion guns. The density was roughly proportional to ion current (1 to 17 mA) and decreased somewhat with increasing ion energy (10 to 37 keV). With D$sub 2$ pressure decrease from 10 to 3 mTorr, n/sub e/ decreased faster than linearly and below approximately 3 mTorr decreased linearly with pressure down to the lowest pressure of 0.4 mTorr. At 1 mTorr and 10 mA, measurements (with poor spatial resolution) were consistent with 10$sup 10$ total electrons and a central n/sub e/ of 10$sup 9$ electrons/cm$sup 3$. Neutron flux (at 50 keV) was about one sixth that of Hirsch (J. Appl. Phys. 38, 4522 (1967)). Six- vs. three-gun operation showed a small enhancement of both n/sub e/ and neutron flux that may indicate some particle trapping.

Structural safety features for superconducting magnets
A survey has been carried out for various potential structural safety problems of superconducting fusion magnets. These areas include: (1) Stresses due to inhomogeneous temperature distributions in magnets where normal regions have been initiated. (2) Stress distributions and yield forces due to cracks and failed regions. (3) Superconducting magnet response due to seismic excitation. These analyses have been carried out using a variety of large capacity finite element computer codes that allow for the evaluation of stresses in elastic or elastic-plastic zones and around singularities in the magnet structure. Thus far, these analyses have been carried out on UWMAK-I type magnet systems. (auth)

Application Of Biometrical Genetics Techniques To Irradiated And Non- Irradiated Populations Of Corn To Provide Information On Nature Of Gene Action Involved In The Inheritance Of Quantitative Traits And In Heterosis. Final Report, 1970.
The purpose of this research was to extend out quantitative genetic investigations into some of the more basic aspects of genetic variation and heterosis observed in irradiated and non- irradiated populations of corn in order to determine more precisely how genes do act and interact to produce their observed cumulative effects.

Cycling indices for ecosystem models
The study of ecosystems is aided by representing structural and functional groups of organisms or processes as discrete components. A complex compartment model will explicitly map pathways from one compartment to another and specify transfer rates. This quantitative description allows insight into the dynamics of flow of nutrients, toxic chemicals, radionuclides, or energy. Three new indices that calculate compartment-specific probabilities of occurrence and recycling and illustrate the problem of applying these indices to ecosystem models are presented.

Development and initial characterization of amorphous metals rich in W and/or RE
Studies of refractory metal alloys concentrated on two families of such alloys: ternary tungsten alloys and binary T/sub 5/-T/sub 9/ alloys. The former were selected because of the possibility of finding desirable glasses consisting of low-cost components; the latter were chosen because they could be quenched into metallic glasses with high thermal stability and good toughness. Alloys selected for study were prepared by arc-melting and were subsequently rapidly quenched in an arc furnace quenching unit. Considerable difficulties were encountered in preparing metal--metalloid alloys, such as W--B, as well as alloys combining high melting and low melting transition metals, such as W and Ni. Brittleness of ductility as revealed by a bend test was noted. Measurements were made up to 1000 K and resistivity measurements up to 1300 K. The probe for electrical resistivity measurements at high temperatures has been constructed and tested. To determine the elastic (Young's) moduli of new metallic glasses prepared in this program, equipment utilizing the pulse--echo method was set up.
