  At the availability of a nonzero mass, the same neutrino regardless of
whether it refers to Dirac or Majorana fermions, must possess simultaneously
each of the anapole and electric dipole moments. Their interaction with the
field of emission can also lead to the elastic scattering of the longitudinal
polarized neutrinos on a spinless nucleus. Using the cross section of a
process, the united equation has been obtained between the anapole and electric
dipole form factors of Dirac and Majorana neutrinos. It corresponds in nature
to the coexistence of neutrinos of both types. As a consequence, each Dirac
neutrino testifies in favor of the existence of a kind of Majorana neutrino.
They constitute herewith the united families of massive neutrinos of a
different nature. Therefore, any of the earlier measured properties of
neutrinos may serve as a certain indication of the existence simultaneously of
both Dirac and Majorana neutrinos. All findings are also confirmed by the
comparatively new laboratory restrictions on the self-masses of these fermions.
Thereby they state that electromagnetic gauge invariance must have a new
structure, which depends on nature of the inertial mass and says that
P-symmetry of a particle is basically violated at the expense of its rest mass.
