Abstract ：We investigate the level structure and $E2$, $M1$ electromagnetic transition properties in an even–even $^{96}$Mo 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 $^{96}$Mo both qualitatively and quantitatively. It is found that both shape coexistence and mixed-symmetry states in $^{96}$Mo 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.
