摘要
By making use of the modified quantum molecular dynamics(MQMD)which includes thePauli potential and the isospin dependent interaction as well as the frictional cooling method for getting aground state of nucleus,the fermionic behavior of nucleons and the distribution of fragments in heavy ioncollisions(HIC)have been studied.The calculated results obviously show the shell effect of fragments.Aqualitative agreement is established between the experimental data and the results of antisymmetrizedmolecular dynamics(AMD)calculation.
