When the mass of the [phi]-particle is negative (-[m.sub.0]), the Muon-neutrino is in enters the Electron-neutrino state and likewise, when mass of the [phi]-particle is positive (+[m.sub.0]), Muon-neutrino enters the r-neutrino state.
* With the result (65) the ratio [??]/[r.sub.N] becomes about [10.sup.6], 40, and 0.4 for the electron-neutrino, muon-neutrino, and the tauon-neutrino.

[2,4] and from electron-neutrino angular correlations in the decay of [.sup.33]Ar [5] is shown in Fig.
The first generation consists of the up and down quarks, which make up protons and neutrons, and the electron and the electron-neutrino. The charm and strange quarks, along with the muon and the muon-neutrino, occupy the second generation.
