Abstract

The level lifetimes of the 2(1)(+) and 4(1)(+) states in Pt-182 have been re-measured employing the gamma-gamma fast-timing technique using fast LaBr3(Ce) scintillators. Excited states in the nucleus of interest were populated by the fusion-evaporation reaction Yb-170(O-16, 4n)Pt-182 at a beam energy of 87 MeV provided by the FN Tandem accelerator of the University of Cologne. The lifetime of the 2(1)(+) state was re-measured with high accuracy to be tau = 563(12) ps and resolves inconsistencies from previous measurements. Experimental results are compared to theoretical calculations in the framework of the sd-IBM with and without configuration mixing.
