Abstract

High spin states of the odd-odd nucleus ¹²²I have been investigated via the fusion-evaporation reaction ¹¹⁶Cd( ¹¹B, 5n) at a beam energy of 68 MeV. The yrast band is extended up to I ^π = (29 ⁺). The band termination at I ^π = (22 ⁺) reported in previous studies is confirmed and interpreted as arising from a shape change from collective prolate to noncollective oblate according to Total-Routhian-Surface (TRS) calculations. In addition, the I ^π=(29 ⁺) state is assigned to the [πh _11/2(πg _7/2) ²] _23/2- ⊗[(νh _11/2) ³(νd _5/2) ²]35/2 ^- configuration corresponding to the full alignment of all valance nucleons outside the semi-closed shell.
