Abstract

New high-K orbitals have been identified in the neutron-rich 181Hf nucleus via one-neutron transfer from a pulsed 238U beam onto a stable 180Hf target. Yrast three-quasiparticle high-K isomers, with half-lives as long as 1.5 ms, have been populated. The decay scheme of 181Hf has been extended to (25/2). Blocked BCS calculations, including residual interactions, compare well with the experimental results.
