摘　　要：We study the average property of isospin fractionation ratio (n/p)free/(n/p)frag induced by halo-neutron nucleus 6He in intermediate energy heavy ion collisions for different beam energies within IQMD. This study is based on the extended density distribution and larger neutron-proton ratio for 6 He which includes obvious effects of isospin dependent interaction and loosely inner structure of 6He on the average property of the isospin fractionation ratio (n/p)free/(n/p)frag as shown in Fig. 1. Fig. 1 shows (n/p)free/(n/We study the average property of isospin fractionation ratio （n/p）free/（n/p）frag induced by halo-neutron nucleus 6He in intermediate energy heavy ion collisions for different beam energies within IQMD.
