In this work, we have presented a microscopic shell-model description of the structure and collective behavior of intermediate-mass nuclei around doubly magic ¹⁰⁰Sn and ¹³²Sn nuclei. The Sn-isotopes lie between the two doubly magic nuclei and cover a range from exotic proton-rich N=Z nuclei to exotic neutron-rich nuclei with N/Z > 1.6. The results obtained using BIGSTICK code for the low-level excitation states and transition probabilities for the studied Sn and Ba isotopic chains have been discussed in the radiance of available experimental data. We have used ¹⁰⁰Sn as a core for all the studied isotopes with the same valence space (i.e. 1d_5/2, 2s_1/2, 1d_3/2, 0g_7/2, 0h_11/2 or ‘sdgh’) for both protons (Z) and neutrons (N) between 50 and 82. These calculations are performed by means of globally optimized monopole effective interaction for the sdgh-shell.

质量区域100-130附近的大规模壳模型计算

在这项工作中，我们提出了一个微观壳模型描述了围绕双魔术¹⁰⁰ Sn和¹³² Sn核的中间质量核的结构和集体行为。Sn同位素位于两个双重魔核之间，覆盖范围从充满异质子的N = Z核到充满异种中子的N / Z> 1.6的核。在现有实验数据的辐射范围内，已经讨论了使用BIGSTICK代码获得的低水平激发态和所研究的Sn和Ba同位素链跃迁概率的结果。对于相同价态空间（即1d _5/ 2，2s _1/ 2，1d _3/ 2，0g _7/2）的所有同位素，我们都使用¹⁰⁰ Sn作为核，质子（Z）和中子（N）在50和82之间都为0h _11/2或“ sdgh”。这些计算是通过对sdgh壳进行全局优化的单极有效相互作用来进行的。
