Description

High-spin states in 190Tl have been studied experimentally by using the 160Gd(35Cl,5n) fusion-evaporation reaction at beam energies of 167 and 175 MeV. A rotational band built on the πh9/2xνi13/2 configuration with oblate deformation has been established for 190Tl. Spin values are assigned by adopting the results from α-γ decay work for 194Bi found in the literature. With the configuration and spin-parity assignments, the low-spin signature inversion has been revealed for the πh9/2xνi13/2 oblate band in 190Tl. It is the first experimental observation of low-spin signature inversion for a band associated with the oblate πh9/2xνi13/2 configuration. The low-spin signature inversion for the oblate πh9/2xνi13/2 band can be interpreted by the two-quasiparticle-plus-rotor model including a J-dependent p-n residual interaction
