Abstract

Excited states in the stable nucleus Ir193 have been investigated through an in-beam γ-ray spectroscopic technique following the Os192(Li7, α2n) reaction at a beam energy of 44 MeV. A level scheme built on the πh_11/2 isomer has been extended to high-spin states using eleven newly observed γ transitions. The πh_11/2 band is proposed to be formed by coupling an h_11/2 proton to a core with large triaxial deformation. Three-quasiparticle states are suggested in Ir193 on referring to the similar states in Ir187. The features of signature splitting in the πh_11/2 bands of 187^-193Ir are discussed with the help of total Routhian surface calculations.
