Abstract：
Excited states in ^188,190Tl have been studied experimentally by means of in-beam γ spectroscopy techniques, and resulted in the identification of a strongly coupled band based on the πh_9/2⊙νi_13/2 configuration with oblate deformation. The oblate band in doubly odd Tl nuclei shows low-spin signature inversion. It is the first experimental observation of low-spin signature inversion for a band associated with the oblate πh_9/2⊙νi_13/2 configuration.
