Intranuclear cascade calculation of high energy heavy ion collisions: Effect of interactions between cascade particles

Abstract

Interactions between cascade particles were included in our intranuclear cascade calculation for high energy heavy ion collisions. This leads to better agreement between the calculated and experimental results for the inclusive pion cross sections and for two-nucleon correlations, without changing appreciably the calculated inclusive proton cross sections. The "single knockout" nucleons are shown to be a small fraction of the inclusive spectra.[NUCLEAR REACTIONS Calculated effect of interactions between cascade particles in the intranuclear cascade model of high-energy heavy-ion reactions.
