Neutron resonance spectroscopy of 117 Sn from 1 eV to 1.5 keV

Parity violation has been studied recently for neutron resonances in {sup 117}Sn. The neutron resonance spectroscopy is essential for the analysis of the parity violation data. We have measured neutron resonances in {sup 117}Sn for neutron energies from 1 to 1500 eV using the time-of-flight method and the (n,{gamma}) reaction. The sample was enriched to 87.6{percent} {sup 117}Sn. Neutron scattering and radiative widths were determined, and orbital angular momentum assignments were made with a Bayesian analysis. The {ital s}-wave and {ital p}-wave strength functions and average level spacings were determined. {copyright} {ital 1999} {ital The American Physical Society}
