摘要

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 an advanced sophisticated algorithm namely the simulated annealing clusterization algorithm ( SACA) along with the conventional spatial correlation method. A quantitative comparison of the mean multiplicity of intermediate mass fragments with experimental findings of the ALADiN group gives excellent agreement showing the ability of the SACA method to reproduce the fragment yields. It also emphasizes the importance of the clustering criterion in describing the fragmentation process within the semi-classical model.
