Neutrino Oscillations. Theory and Experiment
  The theoretical schemes on neutrino oscillations are considered. The experimental data on neutrino oscillations from Super-Kamiokande (Japan) and SNO (Kanada) are given. Comparison of these data with theoretical schemes is done. Conclusion is made that the experimental data have confirmed the scheme only with transitions (oscillations) between aromatic $\nu_e, \nu_\mu, \nu_\tau$ neutrinos with maximal mixing angles.
