Phenomenological Analysis of Characteristics of Rotational Bands in $$^{{158,160}}$$Gd Isotopes

Annotatsiya

Nonadiabatic effects manifested in the energies of states and the probabilities of electromagnetic transitions in $$^{{158,160}}$$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 $${{2}^{ + }}$$, $${{0}^{ + }}$$, and $${{1}^{ + }}$$ levels and the probabilities of $$E2$$-transitions between them are calculated. The mixing effect noticeably affects the wave functions of the band-heads. The calculated energies and probabilities of $$E2$$-transitions are in general satisfactory agreement with experimental data.
