Investigation of Energy Levels and Electromagnetic Transitions for Yb–Pt Nuclei with N=108 Using IBM, IVBM, and BMM

Abstract

The interacting boson and vector boson models, as well as the Bohr-Mottelson one, are employed to describe the energy levels and electromagnetic transitions of the 178 Yb-186 Pt (= 108) nuclei. For the purpose of determining the evolution of the ground state, both ((+ 2)/) and EGOS ratios have been calculated as functions of the spin. Based on the interacting vector boson model and Bohr-Mottelson model, the negative-parity and GSB bands have been calculated, while the interacting boson model is only employed to calculate GSB, , and. The interacting boson model is also used to calculate the reduced transition probabilities (2). The obtained findings show a very well agreement with experimentally obtained results elsewhere. We also used the intrinsic coherent state to obtain the potential energy surfaces. These results indicate that these nuclei have a rotational property SU(3), while 186 Pt has property O(6).
