Inelastic Electron Scattering From Ni58 Ni60 And Ni62

Form factors are reported for the inelastic scattering of electrons from ${\mathrm{Ni}}^{58}$, ${\mathrm{Ni}}^{60}$, and ${\mathrm{Ni}}^{62}$ over the momentum-transfer range from 0.25 to 0.53 ${\mathrm{F}}^{\ensuremath{-}1}$. Reduced radiative transition probabilities $B(\mathrm{EL})$ and transition radii ${R}_{\mathrm{tr}}$ are extracted from the data, notably for the first quadrupole and octupole states of the three isotopes. The transition radii obtained are compared to those of other nuclei.
