Spectra of. rays following the Mo-97(n,gamma) reaction were measured as a function of incident neutron energy with the DANCE (Detector for Advanced Neutron Capture Experiments) array of 160 BaF2 scintillation detectors at the Los Alamos Neutron Science Center using an enriched Mo-97 target. These spectra were used for the assignment of spins of the Mo-97 resonances up to neutron energy E-n = 1.7 keV, as well as in the study of photon strength functions (PSFs) in Mo-98.
Analysis of the spectra with the nuclear statistical model showed that they can be well reproduced with the same PSF models which well described the gamma decay following slow neutron capture in Mo-95. On the other hand, the spectra are inconsistent with PSFs describing some other experimental data in Mo-98.
