A～80区奇——奇核的旋称反转

为了理解奇-奇Rb核正宇称晕带旋称反转的微观起源, 作为一个例子, 用投影壳模型(PSM)计算了核⁸²Rb的能谱. 可以看出计算结果能重现主要的特征. 这个分析清楚地显示只要考虑γ形变随着自旋增加而变化, 旋称劈裂特别是旋称反转就能再现.

Signature Inversion in the Odd-Odd Nuclei with Mass A～80

To understand the microscopic origin of the signature inversion in the yrast positive-parity bands of doubly odd Rb nuclei,as an example,we performed calculations using the projected shell model(PSM)to describe the energy spectra in ~(82)Rb.It can be seen that the main features are reproduced in the calculations. This analysis shows clearly that the signature splitting and especially the signature inversion are reproduced only by a varying T deformation with increasing spin.
