摘要We have studied the fusion reaction for Be-11 + Pb-208 near barrier by applying QMD model, and find that in the fusion reaction induced by halo nuclei there simultaneously exist two mechanisms competing with each other. On one hand, Be-11 is a weakly bound nuclear system and is easily broke up caused by the interaction with target, when it approaches to target, so the fusion cross section is suppressed. On the other hand, several neutrons of Be-11 transfer into Pb-208 and interact with Pb-208 to cause the local radius of Pb-208 increase and result in an enhancement of fusion cross section. The fusion cross sections calculated show an enhancement near barrier, and the calculated results agree with the experimental data reasonably well.
