Elastic and inelastic electron scattering has been carried out on ${}_{}{}^{64}{}_{}{}^{}\mathrm{Ni}$ with $q_{\mathrm{eff}}$ ranging from 0.40 to 1.15 ${\mathrm{fm}}^{\mathrm{-}1}$. Twenty-seven states up to an excitation energy of 6.2 MeV have been identified and spin assignments and electromagnetic transition rates established for 22 states. The comparison of the excitation strengths from electron and alpha particle scattering is not in agreement with the hydrodynamic model for the first $3^{\mathrm{-}}$ transition, but is nearly as expected for the first $2^{+}$ transition.
