Description
The lepton-charge ( Le , Lmu , Ltau ) nonconserving interaction leads to the mixing of
the electron, muon and tau neutrinos, which manifests itself in spatial oscillations
of a neutrino beam, and also to the mixing of the electron, negative muon and
tau lepton, which, in particular, may be the cause of the "forbidden" radiative
decay of the negative muon into the electron and gamma quantum. Under the assumption
that the nondiagonal elements of the mass matrices for neutrinos and ordinary
leptons, connected with the lepton charge nonconservation, are the same, and by
performing the joint analysis of the experimental data on neutrino oscillations and
experimental restriction for the probability of the decay mu- --> e- + gamma per unit time,
the following estimate for the lower bound of neutrino mass has been obtained: m_{ \nu } > 1.5 eV / c^2
