| 摘 要： | The proton and neutron cross-shell excitations across the Z = 50 shell are investigated in the southwest quadrant of 132 Sn by large-scale shell-model calculations with extended pairing and multipole-multipole force. The model space allows proton(neutron) core excitations, and both the low-and high-energy states for 130 In are well described, as found by comparison with the experimental data. The monopole effects between the proton orbit and neutron orbit are studied as the new monopole correction that perfectly reproduces the first 1^+ level in 130 In. The energy interval of proton(neutron) core excitations in 130 In lies in the range of 4.5-6.5(2.0-4.1) MeV, and the high energy yrast states are predicted as neutron core excitations. The decays are calculated among the A=130 nuclei of 130 In, 130 Sn and 130 Cd.
