A simple method was developed for calculating neutron inelastic scattering cross sections. At energies of a few MeV, the direct and compound processes contribute to the cross section, the cross section in any channel at any angle and energy being the sum of the direct interaction and compound nucleus contributions. The direct interaction cross sections were obtained by the distorted wave theory using the computer program CHUCK. The compound nucleus cross sections were calculated from the Hauser-Feshbach theory using the program of Wilmore (1966) with the formalism introduced by Tepel et al (1974) to take account of channels with medium and strong absorption. The results compared well with those from experimental studies and the method was used with some confidence to calculate unknown cross sections.
