在核壳模型的框架内研究了 A = 20 附近松散结合的富质子核的性质。在这些原子核中，涉及松散束缚质子 s(1/2) 轨道的有效相互作用的强度与其镜像原子核中的相比显着降低。我们通过计算伍兹-撒克逊基础上的单极子通用相互作用（V-MU）来评估有效相互作用的减少。因此，可以修改 sd 壳层中的壳层模型哈密顿量，例如 USD，以重现 A = 20 附近弱束缚富质子核的结合能和能级。还讨论了有效相互作用的减少对这些核的结构和衰变性质的影响。
The properties of loosely bound proton-rich nuclei around A = 20 are investigated within the framework of the nuclear shell model. In these nuclei, the strength of the effective interactions involving the loosely bound proton s(1/2) orbit is significantly reduced in comparison with that of those in their mirror nuclei. We evaluate the reduction of the effective interaction by calculating the monopole-based-universal interaction (V-MU) in the Woods-Saxon basis. The shell-model Hamiltonian in the sd shell, such as USD, can thus be modified to reproduce the binding energies and energy levels of the weakly bound proton-rich nuclei around A = 20. The effect of the reduction of the effective interaction on the structure and decay properties of these nuclei is also discussed.
