Abstract and subjects
The gamma rays following the Mo-94,Mo-95(n,gamma) 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 BaF2 scintillation detectors at the Los Alamos Neutron Science Center. The targets were enriched samples: 91.59% Mo-94 and 96.47% Mo-95. The gamma-ray multiplicities and energy spectra for different multiplicities were measured in s- and p-wave resonances up to E-n=10 keV for Mo-94 and up to E-n=2 keV for Mo-95. Definite spins and parities were assigned in Mo-96 for about 60% of the resonances, and tentative spins and parities were assigned for the remaining resonances. In Mo-95 the parities were determined for the observed resonances, confirming previously known assignments.
