摘要

<正>As we know that the density distribution is more extended and the binding energy is decreased as the increase of neutron-proton ratio of neutron-halo nuclei,i. e. ,the inner structure of neutron-halo nuclei is more loose with increasing neutron-proton ratio of neutron-halo nuclei. In this way, it should be a close relationship between the fragmentation violence of neutron-halo projectile and the inner structure of neutronhalo nuclei in heavy ion Collisions. The fragmentation violence of neutron-halo projectile is indicated by the
