Mixing ratios and rotational parameters in 177Lu and 177Hf

The decay of 177mLu, populating high spin states in 177Lu and 177Hf is one of the few cases of radioactive decay, which provide an opportunity to study nuclear properties that are generally observable only in medium or high energy nuclear reactions. From this decay, the g factors (gK, gR) associated with rotational and intrinsic structure of the rotational bands in 177Lu and 177Hf were extracted earlier using the ratio of γ-ray branching intensities (λ) of the intraband crossover and cascade transitions of the rotational levels (J)
