摘　　要：测量了6Li+2 0 8Pb熔合反应近垒能区全熔合截面 ,并与考虑非弹道耦合和不考虑耦合的CCFUS程序计算做了比较 .结果表明在垒上能区 ,破裂使熔合截面减小 ,在垒下能区 。Near barrier fusion excitation function of 6 Li+ 208 Pb system has been measured. The CCFUS calculations with and without the coupled elastic channels taken into account were performed.By comparing the theoretical and experimental results, we can conclude that at the above barrier energies,the fusion cross sections have decreased due to the break up effects,but in the sub barrier energy region,the influence of the break up on the fusion cross section is modest.
