Description
High-spin states in 189Tl have been populated through the 165Ho(28Si,4n) reaction and studied with in-beam γ-ray spectroscopy techniques. Both oblate and prolate structures associated with the i13/2 proton orbit are confirmed and extended to higher spins (19/2 and 41/2, respectively). However, only the oblate structure related to the πh9/2 has been observed meaning that the associated prolate structure is nonyrast contrary to expectation. This experimental result points clearly to a large amplitude of (πh9/2)2 in the wave function of the prolate minimum of 188Hg
