摘要：
Within the framework of an isospin-dependent quantum molecular dynamics model. the multifragmentation in reactions of Sn-112+Sn-112 and Sn-124+Sn-124 at 40 MeV/nucleon is investigated. The calculated results are in good qualitative agreement with the experimental data which indicated that there were significantly different scalings of the mean number of intermediate mass fragments with the number of neutron and charged particles between the two reaction systems. Meanwhile, it is shown that the preequilibrium emission may affect strongly these scalings. [S0556-2813(99)05911-7].
