Decays of , and low-spin states of 181Pt and 177,181Ir

Abstract The decay of 181 Au (T 1 2 = 11.4 s ) has been investigated using mass-separated radioactive sources produced by the ISOCELE facility. Level schemes of 177 Ir, 181 Ir and 181 Pt have been obtained. Most of the levels located at low excitation energy in 181 Ir and 181 Pt are identified as states corresponding to prolate-shaped nuclei. Numerous highly converted transitions have been found in 181 Pt.
