摘要：
The energy levels of excited states of ground state, beta- and gamma-bands of the lanthanide and actinide even-even nuclei have been studied within the Davydov-Chaban model (for three different types of the potential energy of the beta-deformations) and approximations for a small and free triaxiality. It is shown that the approximation with a free triaxiality better describes the spectrum of the excited collective states for considered nuclei.
