In the present work, an investigation of pseudo-mirror nuclei is extended to A~80 mass region. Within the limits of $N_p{N}_n$ approximation, nuclei ⁷²Ge–⁸⁴Sr, ⁷⁶Se–⁸⁰Kr, ⁷⁴Se–⁸²Sr, and ⁷⁶Kr–⁸⁰Sr are identified as pseudo-mirror nuclei. A systematic comparison of their ground-state energy spectra, kinematic moment of inertia, and reduced transition probability B(E2) is presented. Furthermore, we have discussed the purview of the permitted range of $N_p{N}_n$ approximation for pseudo-mirror nuclei.

A∼80 质量区的伪镜核

在目前的工作中，对伪镜核的研究扩展到了 A~80 质量区域。范围内$N_{磷}{N}_n$近似，⁷² Ge– ⁸⁴ Sr、⁷⁶ Se– ⁸⁰ Kr、⁷⁴ Se– ⁸² Sr 和⁷⁶ Kr– ⁸⁰ Sr 核被确定为伪镜核。系统比较了它们的基态能谱、运动惯性矩和降低的跃迁概率 B(E2)。此外，我们已经讨论了允许范围的范围$N_{磷}{N}_n$ 伪镜核的近似值。
