Abstract:
Based on usual QMD, by considering restructured aggregation model, neutron and proton disdinghshing, description of the fermionic behavior of nucleons and frictional cooling method, a new kind of MQMD is proposed. The distribution and time stability of some isotopes in reaction 12C+12C at Elab=28.7MeV/u are studied by this model. The results show that this new MQMD can well describe the structure effect in the fragment formation in HIC.
