Description

Excited states in the stable nucleus 193Ir have been investigated through an in-beam γ-ray spectroscopic technique following the 192Os(7Li, α2n) reaction at a beam energy of 44 MeV. A level scheme built on the πh11/2 isomer has been extended to high-spin states using eleven newly observed γ transitions. The πh11/2 band is proposed to be formed by coupling an h11/2 proton to a core with large triaxial deformation. Three-quasiparticle states are suggested in 193Ir on referring to the similar states in 187Ir. The features of signature splitting in the πh11/2 bands of 187-193Ir are discussed with the help of total Routhian surface calculations.
