Abstract

In this study, we revisit the previous mass relations of mirror nuclei by considering 1/N- and 1/Z-dependent terms and the shell effect across a shell. The root-mean-squared deviation is 66 keV for 116 nuclei with neutron number \(N \ge 10\), as compared with experimental data compiled in the AME2020 database. The predicted mass excesses of 173 proton-rich nuclei, including 98 unknown nuclei, are tabulated in the Supplemental Material herein with competitive accuracy.

镜像核质量关系的改进

在这项研究中，我们通过考虑 1/N- 和 1/Z-dependent 项以及跨壳的壳效应，重新审视了以前镜像核的质量关系。与 AME2020 数据库中的实验数据相比，116 个中子数为（N \ge 10\ ）的原子核的均方根偏差为 66 keV。本文补充材料中列出了 173 个富质子原子核（包括 98 个未知原子核）的质量过剩预测值，其精确度具有竞争性。
