Abstract
A collective vector-boson model with broken SU(3) symmetry is applied to several deformed even-even nuclei. The model description of ground and γ bands together with the corresponding B(E2) transition probabilities is investigated within a broad range of SU(3) irreducible representations (irreps) (λ,μ). The SU(3)-symmetry characteristics of rotational nuclei are analyzed in terms of the bandmixing interactions.
