High spin states of /sup 189/Tl have been populated through the fusion-evaporation reactions /sup 169/Tm(/sup 24/Mg(125 MeV),4n), /sup 165/Ho(/sup 28/Si(140 MeV),4n), and /sup 175/Lu(/sup 20/Ne(128 MeV),6n) and its subsequent decay studied by in-beam /gamma/-ray spectroscopy techniques. Among the firmly established features there are two band structures resulting from the coupling of the h(9/2 and i(13/2 proton intruder states to the oblate ground-state band of the Hg core. However, above a certain excitation energy both bands show structural changes possibly related to the prolate shaped excited band in /sup 188/Hg. At least for the pi-tildei(13/2 case, coexistence of both shapes is observed.
