Nuclear structure studies via neutron interactions: Progress report, July 1, 1986-June 30, 1987

Technical Report ·
OSTI ID:6686295
The research performed during the reporting period consisted of: (1) the analysis of total cross section data for the isotopes of: /sup 48/Ca up to a neutron energy of 4 MeV; /sup 122,124/Sn up to 200 and 300 keV, respectively; and /sup 189/Os up to 170 eV; (3) the preliminary interpretation of these results in the framework of the optical model in an effort to extend the systematics of the potentials deduced from resonance and non-resonance information obtainable from ORELA neutron cross section data; and (4) the interpretation and publication of nuclear structure results for /sub 48/Ca, and the osmium isotopes and their implications for the use of the Re/Os chronometer in estimating the age of the universe. Continued evidence for the 1-dependence of the real well depth of the optical model for neutron elastic scattering from selected target nuclei is seen. Finally, a system for rapid analysis of total neutron cross section data has been developed for microcomputer application which includes the capability for spin and parity assessment for individual resonances and plotting of individual partial wave contributions to the total cross section. This should significantly enhance the study of nuclear structure via neutron interaction. 10 refs., 8 figs., 7 tabs.
