Abstract
Spectroscopic information on the decay properties of high-. K isomers in deformed and transitional nuclei has been evaluated and collated. Assigned multi-quasiparticle configurations are included. Factors that control the transitions strengths, such as various contributions to K mixing, are outlined. The systematics of K-forbidden transitions for different multipolarities are discussed for selected cases in terms of the hindrances, FW, and of the reduced hindrance factor per degree of K forbiddenness, fν, where ν=|δK-λ|, δK is the K-value difference between the initial and final state and λ is the transition multipole order. With the improved statistics for E1, M1 and E2 transitions, a factorization into the product of the underlying multipolarity-dependent transition strength and a ν-dependence, due to K forbiddenness (f0), is possible. This suggests a weaker dependence on K forbiddenness than is commonly assumed.
