Abstract

A level scheme has been constructed for the proton-unbound, Tz=3/2 nuclide 53109I56 following a recoil-decay-tagging experiment using the Ni58(Fe54, p2nγ) reaction at a beam energy of 195 MeV. The experiment was performed using the highly efficient JUROGAM γ-ray spectrometer in conjunction with the RITU gas-filled recoil separator and the GREAT focal-plane spectrometer. Cranking calculations are used to interpret band structures built on πg7/2 and πh11/2 states in a weakly deformed, triaxial nucleus.
