Coriolis mixing significantly affects wave functions of low-lying states.

Calculated B(E2) transition probabilities align with experimental data.

Non-adiabatic effects are important for accurate energy and electric characteristic modeling.

Abstract

Accounting for Coriolis mixing of experimentally known rotational bands with $K^{\pi}< 3^+$, non-adiabatic effects in energy and electric characteristics of excited states are investigated, within phenomenological model. The energy and wave function structure of excited states are calculated. The finding reveals that the bands mixing has been found to have considerable impact on the wave function of low-lying states $0^+$ and $2^+$ bands. In addition, the probabilities of $E2$-- transitions have been calculated. The values from calculations of $B(E2)$-- transitions from $0_2^+$, $0_3^+$, $2_1^+$, and $2_2^+$ bands are compared with the experimental data.
