摘要

We have studied the fragmentation process in heavy ion collisions systematicaIly by using Isospin-dependent Quantum Molecular Dynamics(IQMD)model and found that the multiplicity of intermediate mass fragments N_(imf) can be used as a probe to extract the information of in-medium nmuleon-nucleon cross section.Fig.1 shows
