提出了一种新的有效相互作用，用于由单粒子轨道 p3/2、f5/2、p1/2 和 g9/2 组成的模型空间中的壳模型计算。从核子-核子势导出的实际相互作用开始，通过最小二乘拟合实验能量数据来修改哈密顿参数。由此产生的交互 JUL32 从不同的角度进行了测试。 Gamow-Teller 转变强度的性质在全 pf-壳模型空间中研究，重点关注 56Ni 周围的核，其中壳模型结果显示出对有效相互作用的选择的显着依赖。
A new effective interaction is proposed for shell-model calculations in the model space consisting of single-particle orbits p3/2, f5/2, p1/2, and g9/2. Starting from a realistic interaction derived from the nucleon-nucleon potential, Hamiltonian parameters are modified by a least-squares fit to experimental energy data. The resultant interaction JUL32 is tested from various viewpoints. The property of Gamow-Teller transition strength is studied in the full pf-shell model space focusing on nuclei around 56Ni, where the shell-model results show significant dependence on the choice of the effective interaction.
