摘 要:The entrance channel dependence of the isospin effects of nuclear stopping in intermediate energy heavy-ion collisions has been studied by using an isospin-dependent quantum molecular dynamics with three different kinds of symmetry *** is shown that nuclear stopping is sensitive to the beam energy,the impact parameter and the mass of the colliding system,specially very sensitive to the isospin dependence of in-medium nucleon-nucleon cross section,but insensitive to symmetry potential and the ratio of neutron to proton of colliding *** this *** is proposed that nuclear stopping can be used as a new probe to extract the information on the isospin dependence of in-medium nucleon-nucleon cross section in intermediate energy heavy-ion collisions.
