We consider elastic ${\overline{\nu }}_e{e}^{-}$ scattering taking into account the possible effects of neutrino masses and mixing and of neutrino magnetic moments and electric dipole moments. Having in mind antineutrinos produced in a nuclear reactor we compute, in particular, the weak-electromagnetic interference terms which are linear in the magnetic (electric dipole) moments and also in the neutrino masses. We show that these terms are, however, suppressed compared to the pure weak and electromagnetic cross sections. We also comment upon the possibility of using the electromagnetic cross section to investigate neutrino oscillations.
