Description: This work considers the following problem: what type (Dirac or Majorana) of neutrinos is produced in standard weak interactions? It is concluded that only Dirac neutrinos but not Majorana neutrinos can be produced in these interactions. Then neutrino interacts with Wą and Z bosons but neutrinoless double beta decay is absent. It means that this neutrino will be produced in another type of interaction. Namely, Majorana neutrino will be produced in the interaction which differentiates spin projections but cannot differentiate neutrino (particle) from antineutrino (antiparticle). Then neutrino will interact with Wą bosons and neutrinoless double beta decay will arise. But standard interaction with Z boson will be absent. Such interaction has not been discovered yet. Therefore experiments with very high precision are important to detect the neutrinoless double decay if they are realized in the Nature.
