Isospin dependence of electric-transition probabilities B(E2) in the unitary scheme

In a physical basis of the unitary scheme, analytic formulas for the probabilities B ( E 2 κL → κ′L′ ) and their isospin factors for the ( λ 0) and ( λ 2) 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 lo...

Description
Summary:In a physical basis of the unitary scheme, analytic formulas for the probabilities B ( E 2 κL → κ′L′ ) and their isospin factors for the ( λ 0) and ( λ 2) 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 ( E 2 κL → 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.
