摘要

提出了一种新的、方便的方法来精确计算传统核反应理论中共振宽度(包括亚阈值)和渐近归一化系数等物理量。这种方法可以被认为是通往光核光谱数据完全理论从头描述的道路上的一步。作为该方法的例证,给出了7Li核所有已知态和一些理论预测态的所有相关二体通道的计算结果。在计算中使用了经过大量数据验证的大田16势。所得结果与光谱表中的实验数据基本吻合。

Asymptotic characteristics of decay channels of states of light nuclei in the ab initio approach
A new convenient method for precise theoretical calculations of quantities of traditional theory of nuclear reactions such as widths of resonances (including sub-threshold), and asymptotic normalization coefficients is proposed. This method may be considered as a step on the road to full theoretical ab initio description of light nuclei spectroscopic data. As an illustration of this method the computational results for all relevant two-body channels for all known and some theoretically predicted states of 7Li nucleus are shown. Well-proven on a large amount of data Daejeon16 potential was used in the calculations. The most part of the results turn out to be in a good agreement with the experimental data contained in spectroscopic tables.
