Residual interactions and the K-mixing-induced fast decay of the three-quasiparticle isomer in 171 Tm

Chen, Fang-Qi; Liu, Yan-Xin; Sun, Yang; Walker, Philip M; Dracoulis, George

Description

The anomalously fast decay of a 19/2 + three-quasiparticle isomer in 171Tm was interpreted recently as an example of K mixing induced by a very small mixing matrix element but a (random) close proximity to a collective state. To understand the source of the residual interaction we have generalized the projected shell model by introducing two-body octupole and hexadecupole forces into the Hamiltonian and expanding the model space with inclusion of specific three-quasiparticle configurations. It...[Show more]
