The high-spin levels and decay in neutron-rich hole nuclei of are studied by large-scale shell-model calculations with the extended pairing plus multipole-multipole force model. The excited energy and logft values of decay are predicted in the final states of 128Ag, 128Cd, and 128In by the cascaded decays calculated in hole nuclei. The 16+ level of 128Cd is predicted as a spin-trap isomer feeding the existing high-spin 16+ of 128In by decay. The monopole effects are investigated carefully in the decay process from the ground state 0+ of 128Cd to the 1+ levels of 128In, while the half-life is affected by monopole corrections acting on the configuration of final states.

132Sn 附近的 A = 128 孔核中的高自旋能级、β-衰变和单极子效应
高旋转水平和富中子空穴核衰变通过扩展配对加多极-多极力模型的大规模壳模型计算来研究。的激发能和 logft 值通过在128 Ag、128 Cd 和128 In的最终状态中预测衰变孔核。16 +水平的128 Cd被预测为自旋陷阱异构体,通过衰变。单极子效应在从128 Cd的基态 0 +到128 In 的 1 +水平的衰变过程,而半衰期受作用于最终状态配置的单极校正的影响。
