摘要: We investigate the properties of low-lying states and relevant shape dynamics 98Mo within framework proton-neutron interacting boson model (IBM2). By considering relative energy d proton to be different from that neutron bosons, levels key observable B(E2) transition branching ratios are calculated. The characteristic feature spectrum most crucial available structure indicator indicate substantial mixing between spherical-vibrational γ-unstable shapes in 98Mo. calculation results overall deformation almost same for both ground first excited 0+ states, showing a weak deformation. While triaxiality parameter indicates mostly triaxial with some oblate state, prolate 0+2 being equilibrium
