Phenomenological Analysis of Characteristics of Rotational Bands in Gd Isotopes

— Nonadiabatic effects manifested in the energies of states and the probabilities of electromagnetic transitions in Gd nuclei are studied in the context of a phenomenological model that takes into account Coriolis mixing of low-lying rotational bands. The energies of states of the lowest bands built at the internal , , and levels and the probabilities of -transitions between them are calculated. The mixing effect noticeably affects the wave functions of the band-heads. The calculated energies and probabilities of -transitions are in general satisfactory agreement with experimental data.
