The entrance channel dependence on the isospin effects of the nuclear stopp
ing in intermediate energy heavy ion collisions was studied by using the is
ospin-dependent quantum molecular dynamics with three forms of the symmetry
potential. It shows that the nuclear stopping is sensitive to the beam ene
rgy, 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 neutr
on 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 i
sospin dependence of in-medium nucleon-nucleon cross section in intermediat
e energy heavy ion collisions.
