  The comparison of magnetic moments of neutron and proton reveals three
possible stationary states of a nucleon: s-, p- and o-nucleon with different
configurations and presumably different masses. Two of these nucleons may exist
as the small impurities to the representative one. If so the frequency
1420405751.767 Hz of the hydrogen maser should be accompanied by the lines of
weak intensity with a frequency shift proportional to the mass shift of a
nucleon state. In radio astronomy the manifestation of this can be the presence
of the corresponding "Doppler shifted" lines in the microwave spectrum of
hydrogen.
