标题： Dynamical nucleus-nucleus potential and incompressibility of nuclear matter

摘要： 通过使用改进的量子分子动力学（ImQMD）模型，研究了某些融合反应的动力学核-核势，该模型采用了不同的参数集，其中核物质的压缩系数不同。 提出了ImQMD模型的两个新参数集SKP*和IQ3，其核物质的压缩系数分别为195和225 MeV。 可以合理地再现16O+208Pb的测量融合激发函数以及多碎片化过程中Ca+Ca和Au+Au的碎片电荷分布。 同时，研究了核物质压缩性和核子-核子相互作用范围对核-核动态势的影响。 显示英文摘要

摘要： The dynamical nucleus-nucleus potentials for some fusion reactions are investigated by using the improved quantum molecular dynamics (ImQMD) model with different sets of parameters in which the corresponding incompressibility coefficient of nuclear matter is different. Two new sets of parameters SKP* and IQ3 for the ImQMD model are proposed with the incompressibility coefficient of 195 and 225 MeV, respectively. The measured fusion excitation function for 16O+208Pb and the charge distribution of fragments for Ca+Ca and Au+Au in multi-fragmentation process can be reasonably well reproduced. Simultaneously, the influence of the nuclear matter incompressibility and the range of nucleon-nucleon interaction on the nucleus-nucleus dynamic potential is investigated.
