  We consider theoretically ionization of an atom by neutrino impact taking
into account electromagnetic interactions predicted for massive neutrinos by
theories beyond the Standard Model. The effects of atomic recoil in this
process are estimated using the one-electron and semiclassical approximations
and are found to be unimportant unless the energy transfer is very close to the
ionization threshold. We show that the energy scale where these effects become
important is insignificant for current experiments searching for magnetic
moments of reactor antineutrinos.
