AMD Approach to the Reaction Mechanisms of Intermediate Energy Heavy Ion Collisions(Microscopic Cluster Models of Light Nuclei and Related Topics)

Abstract

Stochastic collision process is incorporated into the antisymmetrized version of molecular dynamics (AMD) as the effect of residual interaction and it is applied to the study of intermediate energy heavy ion reactions. The data of mass distribution of produced fragments in the reaction ^<12>C + ^<12>C at 28.7 MeV/u is reproduced very well, which shows the ability of AMD to describe the shell effect. Momentum distribution of fragments turns out to be sensitive to the stochastic collision process, and the projectile fragmentation appears with the inclusion of nucleon-alpha collisions in addition to the usual two-nucleon collisions in this relatively low energy region.
