Abstract
The rays following the reactions were measured as a function of incident neutron energy by the time-of-flight method with the DANCE (Detector for Advanced Neutron Capture Experiments) array of 160 scintillation detectors at the Los Alamos Neutron Science Center. The targets were enriched samples: 91.59% and 96.47% . The -ray multiplicities and energy spectra for different multiplicities were measured in - and -wave resonances up to keV for and up to keV for . Definite spins and parities were assigned in for about 60% of the resonances, and tentative spins and parities were assigned for the remaining resonances. In the parities were determined for the observed resonances, confirming previously known assignments.
