论文摘要
量子扩散方法扩展到低能融合（捕获）反应和中等质量核的反应。考虑到摩擦参数对轰击能量的依赖性。在极端的亚障碍能力上获得了简单的分析表达。计算出的横截面与实验数据非常一致。比较在量子扩散和WKB方法中计算出的融合激发函数，并在天体物理$ s $ factor表示中进行了比较。
The quantum diffusion approach is extended to low energy fusion (capture) reactions of light- and medium-mass nuclei. The dependence of the friction parameter on bombarding energy is taken into account. A simple analytic expression is obtained for the capture probability at extreme sub-barrier energies. The calculated cross-sections are in a good agreement with the experimental data. The fusion excitation functions calculated within the quantum diffusion and WKB approaches are compared and presented in the astrophysical $S$-factor representation.
