Abstract
The ground state transition probabilities for the 2 1 + states in 90Zr and 60Ni as determined by resonance fluorescence and reorientation effect methods are used as constraints to deduce transition densities from inelastic electron scattering data. The (e, e') cross sections for the 90Zr, 2 1 + state at 2.186 MeV were measured at the Kelvin Laboratory, while for the 2 1 + state at 1.333 MeV in 60Ni, the existing (e, e') data of Yale and Sendai were used. The discrepancy between the model independent (e, e') result of Yale for 90Zr and the (γ, γ') measurement is explained. The importance of an accurate knowledge of the ground state charge distribution for analysis of (e, e') data is emphasized. For 90Zr, the B(E2↑) is 674 ± 60 e 2· fm 4 and R tr is 5.74 ± 0.11 fm. For the 1.333 MeV state in 60Ni, these values are 918 ± 26 e 2· fm 4 and 5.33 ± 0.03 fm respectively.
