Abstract：
We have studied the fusion reaction for ¹¹Be+²⁰⁸Pb near barrier by applying QMD model, and find taht in the fusion reaction induced by halo nuclei there simultaneously exist two mechanisms competing with each other. On one hand,¹¹Be 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 and, several neutrons of ¹¹Be transfer into ²⁰⁸Pb and interact with ²⁰⁸Pb to cause the local radius of ²⁰⁸Pb increase and result in an enhancement of fusion cross section. The fusion cross sections calculatd show an enhancement near barrier, and the calculated results agree with the experimental data reasonably well.
