  • 摘要: 以双幻核132Sn以及附近的空穴核131Sn,130Sn,131In,130In,130Cd为例,研究了大型壳模型计算中的截断效应对该核区能级结构以及电四极跃迁的影响,其中截断包括了有无中子跨壳激发,以及限制轨道粒子数两种情况。计算结果表明,只有在允许质子跨壳激发的情况下才能给出130In与实验相符的基态能级,而允许两个中子的跨壳激发则会改善132Sn的低激发能级结构。此外中子壳芯激发也会对该核区空穴核的低激发能级有一定的影响,相应低能态之间的电四极跃迁则更加敏感地反映出了空间截断效应的影响。


    With two different truncations, i.e., neutron core-excitation truncation and orbital particle-number truncation, the research is studied at the truncation effects in shell-model calculations by the hole nuclei of 130Sn, 131Sn, 130In, 130In and 130Cd. We found that the right ground state of 130In needs proton core-excitation in shell model space, and allowing two neutron core-excitations will promote the low-lying states in 132Sn. The neutron core-excitations will also slightly affect the low-lying levels of hole-nuclei close to 132Sn, and the values of BE2 between the corresponded low-lying states reflect more obviously to the neutron core-excitations.
