Description of spectrum and electromagnetic transitions in ^94Mo through the proton-neutron interacting boson model

We investigated the properties of low-lying states in 94Mo within the framework of the proton-neutron interacting boson model （IBM-2）, with special focus on the characteristics of mixed-symmetry states. We calculated level energies and M1 and E2 transition strengths. The IBM-2 results agree with the available quantitative and qualitative experimental data on 94Mo. The properties of mixed-symmetry states can be well described by IBM-2 given that the energy of the d proton boson is different from that of the neutron boson, especially for the transition of B（M1, 4^＋2→ 4^1＋）.
