Query: Spin Polarization Type Dependence of the Neutrino Mass and Nature   The interaction of longitudinal and transversal polarized neutrinos
(antineutrinos) with the field of a nucleus is investigated at the account of
their rest mass, charge, magnetic, anapole and electric dipole moments. The
compound structure of cross sections in these processes has the sharply
expressed features and generalities for any lepton as well as for a massive
Majorana neutrino. A new influence of truly neutral neutrino masses on the
elastic scattering by nuclei of an electric charge has been discovered which
testifies in favor of the existence of fundamental differences both in the
nature and in the masses of longitudinal and transversal neutrinos of Majorana.
