| 英文摘要 | The influence of medium correction from an isospin dependent nucleon-nucleon cross-section on the fragmentation and nucleon emission in the intermediate energy heavy ion collisions was studied by using an isospin dependent quantum molecular dynamical model (IQMD). We found that the medium correction enhances the dependence of multiplicity of intermediate mass fragment N-imf and the number of nucleon emission N-n on the isospin effect of the nucleon-nucleon cross-section, while the momentum dependent interaction (MDI) produces also an important role for enhancing the influence of the medium correction on the isospin dependence of two-body collision in the fragmentation and nucleon emission processes. After considering the medium correction and the role of momentum dependent interaction the increase for the dependence of Nimf and Nn on the isospin effect of two-body collision is favorable to learn the information about the isospin dependent nucleon-nucleon cross-section.
