On the Gravitational Field of the Electric Charge

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.
