摘要
Within the framework of an IQMD model, multifragmentation in reactions of Sn-112+ Sn-112 and Sn-124+ Sn-124 at 40MeV/u is investigated. The calculated results are in qualitative agreement with the experimental data. Significantly different scalings of the mean IMF multiplicities with neutron, charged-particle, light charged-particle multiplicities, aml Z(bound) are observed for the two reactions. In addition,comparing with the results of expanding evaporating source model and an isospin-dependent percolation model, it is found that the isospin dependence of multifragmentation mainly results from the isospin dependent reaction dynamics.
