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.

Neutron capture cross sections for unstable nuclei in the mass 90 region derived from proton capture measurements. [Strength functions]
Experimental measurements were made of the production cross sections and energy distributions of gamma rays emitted when the stable targets /sup 88/Sr, /sup 89/Y and /sup 90/Zr are exposed to protons in the energy range 3 to 8 MeV. The data are being analyzed using a recent version of the Uhl statistical model code. One conclusion is that while the gamma-ray strength functions employed reproduce the proton capture cross sections, they do not achieve the same degree of hardness observed in the measured spectra. To do so, their lower energy regions must be modified; such changes, however, do not affect the capture cross sections. 7 references.

Vibrational energy transfer in selectively excited diatomic molecules. [Relaxation rates, self-relaxation, upper limits]
Single rovibrational states of HCl(v=2), HBr(v=2), DCl(v=2), and CO(v=2) were excited with a pulsed optical parametric oscillator (OPO). Total vibrational relaxation rates near - resonance quenchers were measured at 295/sup 0/K using time resolved infrared fluorescence. These rates are attributed primarily to V - V energy transfer, and they generally conform to a simple energy gap law. A small deviation was found for the CO(v) + DCl(v') relaxation rates. Upper limits for the self relaxation by V - R,T of HCl(v=2) and HBr(v=2) and for the two quantum exchange between HCl and HBr were determined. The HF dimer was detected at 295/sup 0/K and 30 torr HF pressure with an optoacoustic spectrometer using the OPO. Pulsed and chopped, resonant and non-resonant spectrophones are analyzed in detail. From experiments and first order perturbation theory, these V - V exchange rates appear to behave as a first order perturbation in the vibrational coordinates. The rotational dynamics are known to be complicated however, and the coupled rotational - vibrational dynamics were investigated theoreticaly in infinite order by the Dillon and Stephenson and the first Magnus approximations. Large ..delta..J transitions appear to be important, but these calculations differ by orders of magnitude on specific …

Stress analysis of LOFT penetrations 1A, 2A, 3F, 5A-F, 7A, 9A, 17A-B, 20A-C, 21-A
A stress analysis has been completed for the LOFT piping nozzles penetrating through the containment vessel in accordance with the 1965 edition of Section III of the ASME Boiler and Pressure Vessel Code. LOFT Specification S-1 states that the 1965 edition, including the addenda through the summer 1966 issue, be used. Stresses in the containment wall and in the nozzles result from mechanical and thermal loads on the piping that penetrate the nozzles. The mechanical loads were compiled in LTR 1217-7 and the temperature gradients were provided by the Thermal Analysis Branch. This analysis indicates that the nozzles and the containment wall are adequate to sustain the given mechanical and thermal loads. Therefore, it is recommended that paragraph number S1-04, section M of LOFT specification S-1 be revised to list the nozzle loads presented in Table 3, page A-3a. 9 refs.

Assessment of stress-strain data suitable for finite-element elastic--plastic analysis of shipping containers
Stress-strain data which describes the influence of strain rate and temperature on the mechanical response of materials presently being used for light water reactor fuel shipping containers have been assembled. Selection of data has been limited to that which is suitable for use in finite-element elastic--plastic analysis of shipping containers (e.g., they must include complete material history profiles). Based on this information, recommendations have been made for further work which is required to complete the necessary data base.

Performance of a modified DuoPIGatron ion source for PLT neutral beam injectors
The performance of a modified duoPIGatron ion source for PLT neutral beam injectors is described. The 22-cm source has been operated to deliver beams of 70 A, up to 45 keV, and 0.5 sec. Following a brief review of source operation, the dominant reactions leading to an enhanced atomic ion fraction in the source plasma are emphasized. In addition to the high atomic ion species yield (about 85%), other important characteristics of the source such as high arc efficiency (about 1.1 A ion beam current per kW of arc power), long filament lifetime, high reliability, and scalability are also described.

Analysis of five-spot tracer tests to determine reservoir layering
This report presents a computer algorithm for determining the degree of heterogeneity among the layers of a reservoir. The algorithm uses the equations developed by Brigham and Smith that predict the behavior of a tracer slug flowing in a five-spot injection pattern. To illustrate the use and potential problems in the application of this algorithm, examples are presented using five sets of simulated field test data. One example using actual field data is also presented.
