Microscopic approach to the spectator matter fragmentation from 400 to 1000 AMeV

Abstract

A study of multifragmentation of gold nuclei is reported at incident energies of 400, 600 and 1000 MeV/nucleon using microscopic theory. The present calculations are done within the framework of quantum molecular dynamics (QMD) model. The clusterization is performed with advanced sophisticated algorithm namely \emph{simulated annealing clusterization algorithm} (SACA) along with conventional spatial correlation method. A quantitative comparison of mean multiplicity of intermediate mass fragments with experimental findings of ALADiN group gives excellent agreement showing the ability of SACA method to reproduce the fragment yields. It also emphasizes the importance of clustering criterion in describing the fragmentation process within semi-classical model.
