L. Coraggio, A. Covello, A. Gargano, N. Itaco

摘要:

从134 Sb和210 Bi中质子-中子多重态的惊人相似性出发,我们对具有两个额外质子或中子的核进行了壳模型研究,以了解这种类比在多大程度上持续存在。我们采用有效的相互作用来自CD波恩核子核子势重整化使用的V-low-k方法。对~(136)Sb、~(212)Bi、~(136)I和~(212)At的计算结果与已有的实验数据符合得很好。132 Sn和208 Pb区域之间的相似性进行了讨论,在连接的有效相互作用,强调核心极化效应的作用。

英文摘要:

Starting from the striking similarity of proton-neutron multiplets in 134Sb and 210Bi, we perform a shell-model study of nuclei with two additional protons or neutrons to find out to what extent this analogy persists. We employ effective interactions derived from the CD-Bonn nucleon-nucleon potential renormalized by use of the V-low-k approach. The calculated results for 136Sb, 212Bi, 136I, and 212At are in very good agreement with the available experimental data. The similarity between 132Sn and 208Pb regions is discussed in connection with the effective interaction, emphasizing the role of core polarization effects.
