Abstract
The yrast sequence in (183)T1 has been studied for the first time in recoil -mass selected gamma-ray spectroscopic measurements. A rotational-like casc ade of seven transitions is established down to the band head with probable spin and parity (13/2(+)). Unlike in the adjacent odd-mass T1 nuclei, prom pt gamma decay from the yrast band to a lower lying weakly deformed (oblate ) structure is not observed. These features are consistent with the predict ed drop of the prolate band head in (183)T1 compared to (185)T1. The implic ations for the prolate energy minimum in odd-mass T1 nuclei at the neutron (i)13/2 midshell (N = 103) are discussed.
