摘要

<正> Within the isospin-dependent extended Brueckner-Hartree-Fock ( IEBHF ) framework, the proton and neutron mean free paths in isospin asymmetric nuclear matter and their isospin dependence have been investigated. It is found 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
