Reaction Mechanism forp-Wave Neutron Capture inMo92andMo98

A study of $\gamma$-ray intensities following neutron capture in ${\mathrm{Mo}}^{92}$ and ${\mathrm{Mo}}^{98}$ provides evidence for a simple reaction mechanism which dominates the decay of the compound nuclear state. The intensities are largely accounted for by the motion of a valency neutron in transitions of the type $p_{\frac{3}{2}}\to d_{\frac{3}{2}}$, $d_{\frac{5}{2}}$, or $s_{\frac{1}{2}}$, and $p_{\frac{1}{2}}\to s_{\frac{1}{2}}$ or $d_{\frac{3}{2}}$.
