Magnetic neutrino scattering on atomic electrons revisited

Understand

We reexamine the role of electron binding effects in the inelastic neutrino-atom scattering induced by the neutrino magnetic moment.

• The differential cross section of the process is presented as a sum of the longitudinal and transverse components, according to whether the force that the neutrino magnetic moment exerts on electrons is parallel or perpendicular to momentum transfer.
• The atomic electrons are treated nonrelativistically.
• On this basis, the recent theoretical predictions concerning the magnetic neutrino-impact ionization of atoms are critically discussed.
