Abstract:
Measured E2 transition rates in the N = 50 isotones (90Zr–94Ru) are satisfactorily reproduced by a shell model 0699 0 with proton configurations (p1/2g9/2)n. The inhibited 8+→6+ E2 transition in 94Ru and its connection with seniority mixing is discussed. Isomeric
states are predicted in 91Nb and 93Tc. 0699
