Abstract

Theoretical calculations within the framework of a phenomenological model with Coriolis mixing of states of low-lying positive-parity rotational bands were performed for 156Gd. The Coriolis interaction allows to explain the observed non-adiabaticity effects in the properties of the excited states. Reduced probabilities of the M1 transitions B(M1) and multipole mixing coefficients \(\delta ({{E{\text{2}}} \mathord{\left/ {\vphantom {{E{\text{2}}} {M{\text{1}}}}} \right.} {M{\text{1}}}})\) for transitions from vibrational states were calculated. The behavior of the probabilities of M1 transitions from the mixing states as a function of the total angular momentum was studied. The agreement of the theoretical results with experimental data is, in the whole, satisfactory.
