| Popis: | In a physical basis of the unitary scheme, analytic formulas for the probabilities B(E2κL → κ′L′) and their isospin factors for the (λ0) and (λ2) representations of the SU(3) group were obtained for even-even nuclei. It was shown that the isospin correction must be taken into account at low L and in the case of off-diagonal transitions in κ. The results obtained in the unitary scheme are compared with the results of other models and with experimental data. At high L, the transition probabilities B(E2κL → κ′L′) are markedly smaller in the unitary scheme than in the rotational model, while, for L ≪ λ, these probabilities in the unitary scheme and in the rotational model are close. |
