High-spin states in the neutron-rich nucleus Ta185, populated in the decay of a long-lived, three-quasiparticle state, have been studied using deep-inelastic reactions with Xe136 ions and a W186 target. The lifetime of the isomer has been measured as 17(2) ms and the spin and parity determined to be Kπ=21/2-, leading to a π7/2+ν3/2-11/2+ configuration assignment. The isomer decays into the rotational band built upon the π9/2- intrinsic state via K-forbidden transitions with...[Show more]
