基于Skyrme能量密度泛函结合扩展的Thomas-Fermi近似,研究了原子核的基态性质以及熔合体系的入射道势。另外对于熔合反应,由得到的入射道势构建了一个经验的势垒分布来描述其他自由度对两核相对运动自由度的耦合效应。基于该势垒分布以及势垒穿透思想,许多熔合反应的熔合激发函数能被很好地再现。 Based on the Thomas-Fermi approximation of Skyrme energy density functional expansion, the ground state properties of the nuclei and the incident potential of the fused system are studied. In addition, for the fusion reaction, an empirical barrier distribution is constructed from the incident eigenstates to describe the coupling effects of other degrees of freedom on the relative degrees of freedom of the two nuclei. Based on the barrier distribution and the idea of ​​barrier penetration, the fusion excitation function of many fusion reactions can be well reproduced.
