本文对四个相关邻核的同量异位素类似态建立了一个新的定域质量关系。实验数据线性拟合的标准偏差为20- 70千电子伏。局部质量关系的系统论讨论的经验库仑能量公式和等压多重态质量方程。在微观壳层模型的框架下，研究了核在pf壳层中的局域关系。结果表明库仑相互作用和有效的同位旋非守恒核子-核子相互作用在我们新的质量关系中起着关键作用。
In this paper a new local mass relation is constructed for isobaric analogue states of four relating neighboring nuclei. The standard deviation from a linear fit of experimental data is 20--70 keV. The systematics of the local mass relation is discussed in terms of an empirical Coulomb energy formula and the isobaric multiplet mass equation. The local relation for nuclei in the $pf$ shell is studied in the framework of the microscopic shell model. The results demonstrate the key roles played by the Coulomb interaction and an effective isospin-nonconserving nucleon-nucleon interaction in our new mass relation.
