In this paper, we develop a nonadiabatic collective model for even–even nuclei with effective triaxial quadrupole and octupole deformations. The model describes three-dimensional quadrupole–octupole rotation coupled with axial quadrupole–octupole vibrations. The moment-of-inertia tensor depends on the angular part of the polar coordinates in the quadrupole–octupole space, the values of which are determined from the ground state of the nucleus. In this model framework, the collective states of the yrast-alternating-parity band in the lanthanides [Formula: see text]Sm, [Formula: see text]Gd, [Formula: see text]Dy and the actinides [Formula: see text]Th, [Formula: see text]U, [Formula: see text]Pu are studied.

In the framework of free triaxiality model, branching ratio of reduced E2-transitions probabilities is studied for the full region changes of the triaxiality parameter. The variables of quadrupole deformations [Formula: see text] and [Formula: see text] are dynamic. The Davidson potential for [Formula: see text] and [Formula: see text] variables was used. In the free triaxiality model, the energy levels were obtained by taking into account the high-order terms of the rotational energy operator series, which lead energy levels of ground-state-band, [Formula: see text]- and [Formula: see text]-bands to improve considerably the agreement of the results with experimental data. The quadrupole moment of the nucleus expressed in terms of two internal quadrupole moments: [Formula: see text] is quadrupole moment about the symmetry axis, [Formula: see text] is the measure of the shape asymmetry about the symmetry axis. The intra/inter-band reduced E2-transition probabilities’ ground-state-band, [Formula: see text]- and [Formula: see text]-bands are presented and are expressed in terms of four parameters: [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text]. The influence of [Formula: see text]-oscillations to the reduced probabilities of E2-transitions is taken into account numerically. The sensitivity of the intra-/inter-band reduced E2-transition probabilities to the triaxiality parameter was analyzed.
