High-spin states in {sup 189}Tl have been populated through the {sup 165}Ho({sup 28}Si,4{ital n}) reaction and studied with in-beam {gamma}-ray spectroscopy techniques. Both oblate and prolate structures associated with the {ital i}13/2 proton orbit are confirmed and extended to higher spins (19/2 and 41/2, respectively). However, only the oblate structure related to the {pi}{ital h}9/2 has been observed meaning that the associated prolate structure is nonyrast contrary to expectation. This experimental result points clearly to a large amplitude of ({pi}{ital h}9/2){sup 2} in the wave function of the prolate minimum of {sup 188}Hg.
