Abstract
Excited states in the highly neutron deficient odd-odd nucleus (170)Ir have been investigated. The experiment was performed using the (112)Sn((60)Ni, pn)(170)Ir reaction and employing the recoil-decay tagging technique. Gamma rays were detected using the JUROGAM gamma-ray spectrometer and those belonging to (170)Ir were selected based on recoil identification provided by the RITU gas-filled recoil separator and the GREAT spectrometer at the RITU focal plane. A partial level scheme of (170)Ir is presented for the first time. New alpha-decay branches are assigned to (170)Ir and a tentative level structure for (166)Re is deduced from a study of the alpha-decay fine structure and the associated alpha-gamma correlations.
