Abstract

Excited states in the proton-rich N=84 isotones 72156Hf84,73157Ta84, and 74158W84 were observed using Pd102(Ni58,xp2n) reactions at 270 MeV. γ rays were detected with the Gammasphere array of Compton-suppressed Ge detectors coupled with the Argonne fragment mass analyzer and were assigned to individual reaction channels using the recoil-decay tagging method. Prompt γ-ray cascades were associated with the α decay of both the ground state and the 8+ isomeric state in Hf156, the h11/2 state in Ta157, and the 8+ isomeric state in W158. The level schemes constructed for Hf156,Ta157, and W158 are compared with these of lighter N=84 isotones and are discussed within the framework of the shell model.
