Abstract
High spin states in 188Tl have been investigated via the 157Gd(35Cl,4n) reaction at beam energy of 170MeV. A rotational band built on the πh9/2 otimes νi13/2 configuration with oblate deformation has been established. Considering the similarity between the band structure observed in odd--odd Tl nuclei, spin values have been tentatively proposed for the new band in 188Tl. The πh9/2 otimes νi13/2 oblate band in 188Tl shows low-spin signature inversion, and it can be interpreted qualitatively by the two quasiparticle plus rotor model including a J-dependent p--n residual interaction.
