The level lifetimes of the 2 1 + and 4 1 + states in 182 Pt have been re-measured employing the γ – γ fast-timing technique using fast LaBr 3 (Ce) scintillators. Excited states in the nucleus of interest were populated by the fusion-evaporation reaction 170 Yb (16 O , 4n) 182 Pt 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 τ = 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. [ABSTRACT FROM AUTHOR]
