Abstract

Excited states in the yrast and negative parity bands in 92Mo were populated in two different experiments using the 90Zr(α,2n)92Mo and 93Nb(p,2n)92Mo fusion-evaporation reactions at the Cologne FN Tandem accelerator and measured using a hybrid setup of high purity germanium and lanthanum bromide detectors. Lifetimes of the excited 2_1^+, 4_1^+, 6_1^+, 8_1^+, 5_1^-, 7_1^- and 9_1^- states were measured using the γ-γ fast-timing technique. The newly measured lifetime of the 4_1^+ state differs from the recently published value measured using the recoil distance Doppler shift method. Experimental B(E2) strengths of excited states in 92Mo are used to predict theoretical B(E2) values in the N=50 isotones from 93Tc up to 95Rhusing semiempirical calculations in the single-j orbital 0g_9/2 for the protons.
