Descriptive study of the 120–127Xe isotopes using the IBM-1 and IBFM-1

Abstract

In this work, positive parity low-spin states in 120–127Xe have been investigated using the Interacting Boson Model and the Interacting Boson–Fermion Model. The energy levels, electromagnetic transition B(E2) and B(M1), mixing ratios, relative B(E2) values and the potential energy surface for the even–even 120–126Xe isotopes have been calculated. The theoretical results are compared with the experimental data and it is seen that the obtained theoretical results are in good agreement with the experimental data. The single fermion is assumed to be in one of the 2d5/2, 2d3/2 and 3s1/2 single-particle orbits. Furthermore, the energy levels, electromagnetic transition B(E2) and B(M1) and mixing ratios have been calculated and compared with the experimental data and previous study for even–odd 121–127Xe isotope.
