  • Baced on the quantum molecular dynamics model the special role of neutron-Halo structure in the fragmentation reactions was studied. In order to compare and protrude the special roleof neuron halo structure 11Li in the fragmentation reactions we also studied the fragmentation reactions induced by the stable nucleus 11B with the same mass and the same incident channel condition. We found that the special neutron-halo structure of 11Li is beneficial for the fragmentation reactions in the lower energy region, compared to that induced by stable nucleus 11B. However the beneficial role of neutron-halo 11Li on the fragmentation reactions decreases up to be canceled as the increase of beam energy. The beneficial role of neutron-halo 11Li on the fragmention reactions also decreases as the increases of target mass and impact parameter.

Abstract: Baced on the quantum molecular dynamics model the special role of neutron-Halo structure in the fragmentation reactions was studied. In order to compare and protrude the special roleof neuron halo structure 11Li in the fragmentation reactions we also studied the fragmentation reactions induced by the stable nucleus 11B with the same mass and the same incident channel condition. We found that the special neutron-halo structure of 11Li is beneficial for the fragmentation reactions in the lower energy region, compared to that induced by stable nucleus 11B. However the beneficial role of neutron-halo 11Li on the fragmentation reactions decreases up to be canceled as the increase of beam energy. The beneficial role of neutron-halo 11Li on the fragmention reactions also decreases as the increases of target mass and impact parameter.
