Abstract

A semi-classical model of multi-step direct and compound nuclear reactions is proposed to describe the angular distributions of particles emitted from the inelastic scattering induced by a nucleon with an energy of several tens of MeV. The energy-angle correlation is exactly taken into account for the first few steps of the collision process (multi-step direct process) and the generalized master equation is employed for the following stages of collision process, using the energy-averaged kernelG(Ω → Ω′) (multicompound process). The calculations for197Au(p, p′),120Sn(p, p′) and93Nb(n, n′) show that the model can rather nicely reproduce the experimental data of double-differential cross sections.
