Abstract
The available experimental data on the 14 MeV total (n, p) reaction cross-sections have been brought up to date for the most abundant elements and re-analysed. Marked proton shell and subshell effects and pairing effects are shown to be present. A convenient shell-dependent form of the statistical level density has been developed by using the simple Bloch-Rosenzweig model of combinatorial nuclear structure. This form has been used to estimate quantitatively the observed shell and subshell effects.
