Neutron resonances inMo100and valence neutron capture

Neutron resonance interactions with ${}_{}{}^{100}{}_{}{}^{}\mathrm{Mo}$ were studied at a time-of-flight facility. The transmission of two oxide samples (97.4% ${}_{}{}^{100}{}_{}{}^{}\mathrm{Mo}$) was measured at a 78.20 m flight path and the neutron capture cross section was measured at 40.12 m. Resonance analyses yielded parameters of 124 resonances. Capture $\gamma$-ray spectra from 11 resolved resonances were measured with a Ge(Li) detector at a 10.45 m flight path. In contrast to neighboring nuclei, partial radiation widths of strong $p$-wave resonances are not in agreement with valence model predictions.
