| 英文摘要 | Based on the isospin dependence of quantum molecular dynamics with momentum dependent interaction, the dependence of symmetrical potential and isospin dependence of inmedium nucleon-nucleon cross section on the nuclear stopping were studied in wider beam energy region (45-150MeV/u) for four colliding systems with different ratios of neutron-proton.. The calculation results show that the nuclear stopping depends strongly on the isospin dependence of in-medium nudeon-nucleon cross section sigma (iso) and weakly on symmetrical potential U-sym for the all of colliding systems in wider beam energy region studied here. It is suggested that the information on the isospin dependence of in-medium nucleon-nucleon cross section could the extracted from the comparisons between the theoretical results and the experiment data on the nuclear stopping in the process of intermediate energy heavy ion collisions. The dependence of the nuclear stopping on sigma (iso) is very sensitive to beam energy E-L, and impact parameter b. The results also show that the effect of momentum dependence interaction on the nuclear stopping is important. |
