Triaxial rotor model for the study of the nuclear structure and transition between different symmetries in nuclei for A = 120-200 mass region

Abstract

The rigid triaxial rotor model used to search the dependence of ROT(E)/ 1 (2 ) E + and SF(E)/ 1 (2 ) E + on the mixing effect of asymmetric parameter (γ) and mixing angle (τ). The dependence of γ and deformation parameter (β) on the energy ratio (R4/2) is discussed. It can be found that the calculated energy, B(E2) values have reasonable agreement with the experimental energy, B(E2) values and B(E2) ratios.
