A~80区奇-奇核的旋称反转(英文)
Signature Inversion in the Odd-Odd Nuclei with Mass A~80
【摘要】 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.
【Abstract】 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 82Rb.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.
