Due to the rotation of the frame, neutrino is observed as a superposition of two states P-transformed one from another. Since P-transformation is forbidden for neutrino, in the rotating reference frame one can detect a half of neutrino flux. Due to the rotation of the earth, the detector of neutrinos can measure a half of the solar neutrino flux predicted by the SSM that may provide a solution for the solar neutrino puzzle.2 pages, LaTeXGeneral Physicstext
