采用扩展的对加多极-多极力模型，通过大尺度壳模型计算，研究了A= 128丰中子空穴核的高自旋能级和β−衰变.通过计算A= 128空穴核的级联衰变，预测了128 Ag、128 Cd和128 In末态β−衰变的激发能和logft值。128 Cd的16+能级被预测为自旋陷阱异构体，通过β−衰变补充现有的128 In的高自旋16+。仔细研究了128 Cd从基态0+到128 In的1+能级的β−衰变过程中的γ效应，而半衰期则受到γ修正对末态组态的影响。
The high-spin levels and β− decay in neutron-rich hole nuclei of A= 128 are studied by large-scale shell-model calculations with the extended pairing plus multipole-multipole force model. The excited energy and logft values of β− decay are predicted in the final states of 128 Ag, 128 Cd, and 128 In by the cascaded decays calculated in A= 128 hole nuclei. The 16+ level of 128 Cd is predicted as a spin-trap isomer feeding the existing high-spin 16+ of 128 In by β− decay. The monopole effects are investigated carefully in the β− decay process from the ground state 0+ of 128 Cd to the 1+ levels of 128 In, while the half-life is affected by monopole corrections acting on the configuration of final states.
