Abstract：
The entrance channel dependence on the isospin effects of the nuclear stopping in intermediate energy heavy ion collisions was studied by using the isospin-dependent quantum molecular dynamics with three forms of the symmetry potential. It shows that the nuclear stopping is sensitive to the beam energy, the impact parameter and the mass of the colliding system, especially very sensitive to the isospin dependence of in-medium nucleon-nucleon cross section, but insensitive to the symmetry potentials and the ratio of neutron to proton of colliding system. From this investigation, we propose that nuclear stopping can be used as a new probe to extract information on the isospin dependence of in-medium nucleon-nucleon cross section in intermediate energy heavy ion collisions.
