  The idea has been spoken that any of Dirac and Pauli form factors of leptonic
current includes both normal and anomalous components. From this point of view,
the dependence of independent parts of charge and magnetic moment is
established with the use of cross sections of elastic scattering of unpolarized
and longitudinal polarized electrons and their neutrinos by spinless nuclei.
Some considerations of a connection between the mass of a particle and its
electromagnetic nature are listed which can explain also the appearance of
gravitational field of a Coulomb interaction. All they state that a massive
four-component neutrino similarly to the electron must have the normal as well
as the anomalous electric charge.
