Momentum distribution of fragments in heavy ion reactions: Dependence on the stochastic collision process

Abstract

Momentum distribution of fragments produced in 12C+12C reaction at 28.7 MeV/nucleon is analyzed with antisymmetrized version of molecular dynamics (AMD). Calculations are made for several cases of stochastic collisions and the projectile fragmentation peak in momentum distribution is reproduced by the incorporation of many-body nature in stochastic collision process. Furthermore the value of the cross section is found to be reflected in the low momentum part of fragments such as alpha particles and 9Be.
