Competition between high-K states and rotational structures in 177Ta

Dasgupta, Mahananda; Dracoulis, George; Walker, P M; Byrne, Aidan; Kibedi, Tibor; Kondev, F.; Lane, Gregory; Regan, P.


High-spin states in 177Ta have been studied using the 170Er(11B,4n) reaction. New intrinsic states have been observed corresponding to 3-, 5-, and 7-quasiparticle high-K structures. Rotational bands built on most of the 3-and 5-quasiparticle states and some transitions above the 7-quasiparticle states have been identified. Several isomers have been found, the longest lived being the 49/2-, 7-quasiparticle state with a meanlife of 192 μs. Configurations for the observed intrinsic states have...[Show more]
