| 英文摘要 | The role of momentum dependence equation of state on the nuclear stopping for the isospin dependence and the isospin independence of in-medium nucleon-nucleon cross section is studied by using the isospin dependence quantum molecular dynamics. The nuclear stopping depends strongly on the isospin dependence of in-medium nucleon-nucleon cross section and weakly on the isospin dependence of the mean field-symmetry potential from above the Fermi energy to about 15OMeV/u for the small impact parameters. A detail study indicates that the difference between the nuclear stopping for the isospin dependence and the isospin independence of in-medium nucleon-nucleon cross section depends sensitively on the momentum dependence interaction, namely, the difference between the nuclear stopping for the isospin dependence and the isospin independence of in-medium nucleon-nucleon cross section in the present of momentum dependence interaction is larger than that without the momentum dependence interaction (MDI) for the mass symmetry and mass asymmetry reaction systems, neutron-rich and neutron-poor reaction systems. Namely, MDI increases the sensitivity of the nuclear stopping on the isospin dependence nucleon-nucleon cross section. Therefore, the knowledge on the isospin dependence of in-medium mucleon-nucleon cross section can be extracted more accurately from nucleon stopping as a probe if the momentum dependence interaction is taken into account. |
