Competition of rotation around the intermediate and long axes in 193Tl
Abstract
High-spin states in 193Tl were studied and the level scheme was revised and extended including the observation of new rotational bands. A surprising competition between bands built on the same π h9 /2⊗ν i13/2 -2 nucleon configurations is observed. It is suggested that it is generated by two different rotational modes of this triaxial nucleus: (i) a rotation around the intermediate nuclear axis, producing a pair of chiral symmetry bands, and (ii) a rotation around the long nuclear axis, producing a third band with lower alignment.
