A unified description of shape coexistence and mixed-symmetry states in 98Mo using IBM-2*

Cheng-Fu Mu(穆成富),Da-Li Zhang(张大立)

Table 2. Experimental E2 and M1 transition strengths for 98Mo are compared to the calculated ones, where E2 strengths are given in unit of W.u., and the M1 transition are given in unit of ${\mu }_{N}^{2}$. The experimental data are adopted from [4–6].
