Abstract

The Coriolis matrix elements responsible for mixing of the \(1^+ K=1\) and \(1^+ K=0\) states are calculated in the framework of the Quasiparticle Phonon Model for several Gd and Dy isotopes. In many considered cases these matrix elements are equal to several tens of keV and are comparable with energy distances between the mixed levels. The results obtained indicates that Gd isotopes could be more suitable for finding deviations from Alaga rules in M1 transitions from \(1^+\) state to the states of the ground band.
