英文摘要	The isospin effects on the fragmentation process and the role of momentum dependent interaction in heavy ion collisions at intermediate energy are studied systematically by using isospin dependent Quantum Molecular Dynamical model (IQMD). The results show that multiplicity of intermediate mass fragments (b) averaged over all impact parameters depends on the isospin effects of in-medium nucleon-nucleon cross section strongly but on the symmetry potential weakly. The momentum dependent interaction enhances the sensitivity of N-imf to the isospin effects of in-medium nucleon-nucleon cross section. Therefore, (b) can be used as a probe to extract the information of in-medium isospin-dependent nucleon-nucleon cross section in heavy ion collisions at intermediate energy.
