Abstract
The problem of the very different E2 decay rates from the two-quasineutron Kπ = 6+ isomers in the N = 104 isotones 172Er, 174Yb, 176Hf, and 178W is investigated using the triaxial projected shell model with inclusion of multi-quasiparticle configurations. It is demonstrated that the highly K-forbidden transition from the 6+ isomer to the ground-state band is sensitive to mixing with the 6+ state of the γ-vibrational band. Thus the inter-band transitions, and lifetimes, depend on the relative position of the γ-band and the isomeric state in each isotone.
