A STUDY OF E2 OPERATOR IN U(15) MODEL FOR DEFORMED NUCLEI

  • In this paper, the E2 operator in the scheme of U(15) model is studied by means of varying the parameters in the E2 operator itself. If is shown that, compared with the U(6) model, the U(15) model has some advantages in explaining the flexibility of the ratio of the E2 transition probabilitys between different bands, the behavior of B(E2) at high-spin states and transitions between high bands.

A STUDY OF E2 OPERATOR IN U(15) MODEL FOR DEFORMED NUCLEI

  • Suzhou University

Abstract: In this paper, the E2 operator in the scheme of U(15) model is studied by means of varying the parameters in the E2 operator itself. If is shown that, compared with the U(6) model, the U(15) model has some advantages in explaining the flexibility of the ratio of the E2 transition probabilitys between different bands, the behavior of B(E2) at high-spin states and transitions between high bands.
