In weak-interaction models with spontaneous parity nonconservation, based on the gauge group SU (2) ₋ (2) ₑ (1), we obtain the following formula for the neutrino mass: m₄{m₄^2}g{mₖₑ}, where Wₑ is the gauge boson which mediates right-handed weak interactions. This formula, valid for each lepton generation, relates the maximality of observed parity nonconservation at low energies to the smallness of neutrino masses.
