- Abstract
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 β 2 and γ are dynamic. The Davidson potential for β 2 and γ 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, β - and γ -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: Q 0 is quadrupole moment about the symmetry axis, Q 2 is the measure of the shape asymmetry about the symmetry axis. The intra/inter-band reduced E2-transition probabilities' ground-state-band, β - and γ -bands are presented and are expressed in terms of four parameters: μ β 2 , μ γ , γ 0 and Q 0 . The influence of γ -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.
