Abstract

We investigate the level structure and E2, M1 electromagnetic transition properties in an even–even 96Mo nucleus within the framework of the proton–neutron interacting boson model (IBM-2). The calculated results of the IBM-2 can reproduce the recent new experimental data on 96Mo both qualitatively and quantitatively. It is found that both shape coexistence and mixed-symmetry states in 96Mo can be simultaneously described very well with the IBM-2 by taking into account that the relative energy of d neutron bosons is different from that of proton bosons.
