摘要

High-spin isomeric decays in Hf-174 and Hf-175 are found to populate a large number of different quasiparticle structures. Many weak gamma-ray transitions are revealed that violate the usual K-selection rules, Analysis of transition hindrance factors shows the importance of K-mixing in the populated levels. The effects of both chance near-degeneracies and Coriolis coupling are separately identified. The role of high-K components in Fermi-aligned ''tilted'' bands is emphasized. The 4-quasiparticle excitation energies are compared with the sum of the constituent 2-quasiparticle energies. [References: 27]
