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 ${\mathrm{F}}^{-1\mathrm{}}$. Reduced radiative transition probabilities $B\left(\mathrm{EL}\right)\mathrm{}$ 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.
