Abstract：
Within the isospin dependent extended Brueckner-Hartree-Fock framework, the proton and neutron mean free paths in isospin asymmetric nuclear matter and their isospin denpendence have been investigated. It is shown that as increasing the isospin asymmetry, the proton mean free path decreases while the neutron one increases. This implies that the surface of a neutron-rich nuclei near drip-line will be much more transparent for neutrons than for protons. The density dependence of the mean free paths and the effect of the ground-state correlations on the mean free paths have also been discussed.
