Description of spectrum and electromagnetic transitions in [sup.94]Mo through the proton-neutron interacting boson model

We investigated the properties of low-lying states in [sup.94]Mo 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 wi...

Description
Summary:We investigated the properties of low-lying states in [sup.94]Mo 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 [sup.94]Mo. 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.sup.+.sub.2] [right arrow] [4.sup.+.sub.1]).
