论文摘要
在$^{195} $ a \ sim190 $区域中为Doublet Band B2和B2A建议的手性。电势曲线和配置以及变形参数是通过约束协变量功能理论获得的。相应的实验能光谱，双重频带之间的能量差异以及可用的$ b（m1）/b（e2）$值由全质量粒子转子模型研究。根据角动量成分，$ K $图和方位角的分析，提出了B2和B2A频段的平面旋转解释。因此，它与$^{195} $ tl中的其他双重乐队B4和B4A中的Aplanar旋转并存。
The chirality suggested for the doublet bands B2 and B2a in $^{195}$Tl in $A\sim190$ region is reexamined. The potential-energy curves and the configurations together with the deformation parameters are obtained by the constrained covariant density functional theory. The corresponding experimental energy spectra, energy differences between doublet bands, and the available $B(M1)/B(E2)$ values are investigated by the fully quantal particle rotor model. Analysis on the basis of the angular momentum components, the $K$-plots, and the azimuthal plots suggest a planar rotation interpretation for the bands B2 and B2a. Hence, it coexists with the aplanar rotation in the other doublet bands B4 and B4a in $^{195}$Tl.
