论文摘要
众所周知，对称性在SN同位素的低级别级别结构中起着重要作用，主要是在资历和普遍的资历计划方面。在本文中，我们重新访问CD中的第一个兴奋的$ 2^+$和$ 3^ - $状态的多J广义资历方法（$ z = 48 $），SN（$ Z = 50 $）和TE（$ Z = 52 $）同位素，CD和TE同位素是CD和Te iSotopes代表两种孔和两种颗粒核的核心，因此涉及sn的sn，因此涉及SNINONS（sn），并涉及核心（Intons）（含量）（源）（属于核心）（蛋白质源）（蛋白质）（含量均应涉及核心（Intons）（蛋白质）（蛋白质核）（含量均参与其中（含量）（蛋白质）（涉及四个蛋白酶）（蛋同位素。有趣的是，仅基于中子价空间的方法就可以分别以$ 2^+$和$ 3^ - $状态在所有三个CD，SN和TE同位素中分别解释B（E2）和B（E3）趋势。 CD和TE同位素中B（E3）值倒抛物面行为的新结果以与SN同位素相同的方式使用通用的资历方案来理解。这些计算不支持壳淬火；因此，中子魔术数字，$ n = 50 $和$ n = 82 $，在这些同位素链中保持强大。令人惊讶的是，普遍的资历继续在半魔术区域中取得合理的成功，从而提供了$ 2^+$和$ 3^ - $州的统一视图。
Symmetries are known to play an important role in the low lying level structure of Sn isotopes, mostly in terms of the seniority and generalized seniority schemes. In this paper, we revisit the multi-j generalized seniority approach for the first excited $2^+$ and $3^-$ states in the Cd ($Z=48$), Sn ($Z=50$) and Te ($Z=52$) isotopes, where the Cd and Te isotopes represent two-proton hole and two-proton particle nuclei, thus involving both kind of particles (protons and neutrons) in contrast to Sn isotopes. Interestingly, the approach based on neutron valence space alone is able to explain the B(E2) and B(E3) trends respectively for the $2^+$ and $3^-$ states in all the three Cd, Sn and Te isotopes. The new results on the inverted parabolic behavior of B(E3) values in Cd and Te isotopes are understood in a manner identical to that of Sn isotopes by using the generalized seniority scheme. No shell quenching is supported by these calculations; hence, the neutron magic numbers, $N=50$ and $N=82$, remain robust in these isotopic chains. It is quite surprising that the generalized seniority continues to be reasonably successful away from the semi-magic region, thus providing a unifying view of the $2^+$ and $3^-$ states.
