Davydov–Chaban model formalism with Davidson potential

The Davydov–Chaban model formalism with the Davidson potential for describing the spectrum of excited collective states of heavy even–even nuclei is considered. At describing the energy levels of the ground-state, [Formula: see text]- and [Formula: see text]-bands, the K-mixing effect created by model triaxial rotations is taken into account. The energy spectra of the ground-state, [Formula: see text]- and [Formula: see text]-bands of heavy even–even nuclei: [Formula: see text]Sm [Formula: see text]Gd, [Formula: see text]Dy, [Formula: see text]Er, [Formula: see text]Hf, [Formula: see text]Yb, [Formula: see text]W, [Formula: see text]Th, [Formula: see text]U and [Formula: see text]Pu are considered. The coupling of the ground-state band and the [Formula: see text]-band is also considered. In the framework of presented model formalism, intra-ground-state-band reduced E2-transition probabilities were studied.
