The yrast sequence in {sup 183}Tl has been studied for the first time in recoil-mass and decay tagged {gamma}-ray spectroscopic measurements. A rotational-like cascade of seven transitions is observed down to the bandhead with spin 13/2{sup +}. In contrast to adjacent nuclei, links from the yrast band to a lower lying weakly deformed (oblate) structure are not observed. It appears that the prolate energy minimum in {sup 183}Tl drops significantly compared to {sup 185}Tl and minimizes below the neutron i{sub 13/2} midshell (N{<=}102). Possibilities for the decay out of the band in {sup 183}Tl are discussed. (c) 1999 American Institute of Physics.
