ABSTRACT
The possible reasons of features of the nature of neutrino are discussed.
Keywords: Neurino; Oscillations; Masses
Earlier we with use of experimental data on neutrino
oscillation [1] had been calculated neutrino masses [2].
Such problem has been solved with use of left-right
gauge group 2 following the ap proach of
[3] with some changes.

Phenomenon of small masses of neutrinos appears ra-
ther essential. There comes a threshold of stability of
discrete character of masses of neutrinos and enough free
transition from one generation to another. For compari-
son we result masses of partners of neutrino on the weak
charged currents at which birth oscillations is absen t:

That is certain proportionality of masses of generations
of neutrinos and sine of corners of mixing is observed.
The more masses of pair neutrinos differ from each other
the less between them a mixing sine of the angle. For
example, mixing usual neutrinos and sterile neutrinos
with rather big masses will be suppressed.
It is necessary to tell that in direct measurement neu-
trino oscillation there is a problem of statistical uncer-
tainty at definition of parametres. Use of two various
mixing matrixes in calculation of parametres will appear
useful. Also there will be useful in processing of results
of these experiments use of ad ditional criteria ex cept

There is some affinity of neutrino with photons in-
cluding in the cosmology plan. Photon is some twirled
whirlwind of energy with spin and with zero
mass. Neutrino has spin 1S

relation to relic radiation of photons. Direct detecting of
relic neutrinos is unsoluble at present a problem.
Since introduction of technics of research of neutrino
oscillation by B. Pontecorvo a little that has changed in
understanding of the essence of this phenomenon. The
version of this understanding offered by us is some step
to this direction.
From the point of view of the justification of our ap-
proach on experiment the result of measurement of mass
of smallest of leptons—an electron testifies at least:

error is equal to 0.013 eV and means in the order of size

Obviously, that masses of sterile neutrinos do not get
to area of masses of three generations of neutrinos. If
sterile neutrino exist, their masses of essentially more
masses of usual neutrinos. The prediction in our work is
instructive that their mixing with usual neutrinos will be
suppressed. This remark will not appear superfluous for
researchers-experimenters.
