Coexistence of planar and aplanar rotations in 195Tl

Coexistence of planar and aplanar rotations in 195Tl

The chirality suggested for the doublet bands B2 and B2a in 195Tl in A∼190 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 spec...
