Abstract：
We have used the isospin dependent quantum molecular dynamics to investigate the probable observable for probing isospin dependent nucleon-nucleon cross section in multifragmentation process of intermediate energy heavy ion collisions. The calculation results show that the correlation between the intermediate mass fragment multiplicity N_imf and the total number of charged particles N_c is a sensitive observable for probing in medium isospin dependent nucleon-nucleon cross section in the chosen energy region. Because we apply the reversible reaction effect of heavy mass projectile on light mass target in the chosen energy region, which result in more intermediate mass products emitted towards forward angles, it is convenient to extract in medium isospin dependent nucleon-nucleon cross sections by combining theory simulations and experimental observations under the conditions of limited detectors.
