Abstract

High-K states in the region of ¹⁷⁷Lu have been studied using multi-nucleon transfer reactions with ¹³⁶Xe beams and Gammasphere. Results include identification of the predicted 5-quasiparticle K^π = 39/2 ^- isomer in ¹⁷⁷Lu, a 7-quasiparticle K ^π = 49/2 ⁺ isomer in ¹⁷⁹Ta with an anomalously fast decay, and numerous other examples in a range of Yb close to stability. The results are discussed in the context of the expectations for multi-quasiparticle states near Z = 72 and the factors which may both govern isomer formation and also give an insight into K-purity, specifically chance degeneracies, and statistical mixing above the yrast line.
