Description

High-spin states in rotational bands associated with the 11/2-[505], 1/2-[541] and 1/2+[660] Nilsson orbits have been observed in the previously unknown 173Ir nucleus using the 144Sm(32S, p2n) reaction at 163 MeV. The B(M1;I→I-1)/B(E2;I→I-2) ratios have been extracted for the 11/2-[505] band and compared with predictions of the semiempirical model by Doenau and Frauendorf. The quasineutron band crossing frequencies and alignment gains are discussed in terms of the CSM model. Calculations for equilibrium deformation suggest different deformations for the three bands observed. (orig.)
