Model study of alpha-induced reactions

Abstract

Inclusive spectra of protons, deuterons, tritons, ³He, and ⁴He particles from alpha induced reactions have been investigated through model calculations, mainly to improve a theoretical model for understanding the mechanism of cluster-induced reactions. In this report, the intranuclear cascade (INC) model, developed at Kyushu University, has been extended for alpha induced reactions. The incident alpha particles are assumed to break up into fragments stochastically at the initial or the final interaction with the target nucleus. The momentum of a fragment is assumed to be the vector sum of constituent nucleons. Then fragments and particles may undergo the cascade process. Model calculations show reasonable agreement with the experimental data.
