Average Property of Reaction Mechanism Induced by Halo-neutron Nucleus 8He with Measure of Neutron-proton Ratio of Nucleon Emissions

摘要

We study the average property of reaction mechanism induced by halo-neutron nucleus 8He in intermediate energy heavy ion collisions as a function of beam energy with IQMD. This study is based on the extended density distribution and larger neutron-proton ratio for 8He which includes obvious effects of isospin dependence of interaction and loosely inner structure of 8 He on the average property of
