Abstract
In this work, non-adiabatic effects manifested in the magnetic properties of ground band in even–even deformed nuclei are studied. A simple phenomenological model, which takes into account the Coriolis mixing of states of the ground and bands, is proposed. Using perturbation theory, corrections to the wave functions of states are determined. In addition, an analytical expression to determine the gR-factor of the states of ground rotational band is obtained. The decrease in gR-factor with increasing angular momentum I is discussed. The accuracy of the approximation is verified. The determined values of wave functions of different methods are found to be close to each other.
