Abstract：
Based on the light charged particles and fragments emitted towards forward angles by using the heavy projectile on the light target, we have made use of isospin-dependent quantum molecular dynamics to investigate a sensitive probe on the isospin effects in the process of intermediate energy heavy ion collision. The calculation results show that the correlation between the multiplicity of intermediate mass fragments and the total number of charged par- ticles in the energy region above 80MeV/u is a sensitive probe on the isospin-dependent nucleon-nucleon cross section in medium in intermediate energy heavy ion collision, meanwhile the isospin effects of symmetric energy is not obvious in the same energy region.
