Cluster Approach to Intranuclear Cascade for Relativistic Heavy-Ion Collisions

Abstract

A new approach to the intranuclear cascade model for relativistic heavy-ion reactions is presented. The effect of nucleon concentration on the collision process is explicitly included. It is found that the contributions from the nonbinary processes are far from being negligible. Such processes are shown to broaden the angular distribution of inclusive proton spectra for ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$+ ${}_{}{}^{238}{}_{}{}^{}\mathrm{U}$ head-on collisions.
