标题： Complete Fusion Enhancement and Suppression of Weakly Bound Nuclei at Near Barrier Energies

摘要： 我们考虑在动态极化势的框架下，断裂通道对弱结合系统完全融合的影响。 认为在低于势垒能量处截面的增强可能与最近的实验观测一致，即核子转移（通常导致断裂）相比直接断裂更为显著。 在DPP方法的框架下分析了$^{6,7}$Li + $^{209}$Bi 实验完全融合截面的主要趋势。 显示英文摘要

摘要： We consider the influence of breakup channels on the complete fusion of weakly bound systems in terms of dynamic polarization potentials. It is argued that the enhancement of the cross section at sub-barrier energies may be consistent with recent experimental observations that nucleon transfer, often leading to breakup, is dominant compared to direct breakup. The main trends of the experimental complete fusion cross section for $^{6,7}$Li + $^{209}$Bi are analyzed in the framework of the DPP approach.
