Abstract：
High-spin Level structure of ¹⁸⁸Tl has been studied via ¹⁵⁷Gd(³⁵Cl,4n) fusion-evaporation reaction at beam energy of 170MeV. A rotational band built on the πh_9/2×υi_13/2 configuration with oblate deformation has been established. Spin values have been proposed to the πh_9/2×υi_13/2 oblate band based on the similarities between the oblate band of ¹⁸⁸Tl and those in odd-odd ^190—200Tl. With the spin assignments, the low-spin signature inversion has been revealed for the πh_9/2×υi_13/2 oblate band of ¹⁸⁸Tl. The low-spin signature inversion can be interpreted qualitatively in the framework of the quasi-particles plus rotor model including a J dependent p-n residual interaction.
