Nuclear Structure of Ce Nuclei within Interacting Boson Model-2

Abstract

Using the Interacting Boson Model-2 (IBM-2), we determined the most appropriate Hamiltonian for the current calculations of energy levels and electromagnetic transition probability values of 124-138Ce nuclei with a mass around A=140  in this study. We estimated energy levels and electromagnetic values and mixing ratios (E2/M1)  for a number of transitions in 124-138Ce isotopes using the best fitted values of parameters in the IBM-2 Hamiltonian. When the results were compared to the experimental data, they were found to be in good agreement.
