Abstract:
A low energy electron beam (leq1200 eV) is injected perpendicularly to a uniform magnetic field, together with a low energy positive ion beam which is stopped electrically. On these magnetic mass analyses (using the uniform magnetic field), two peaks of secondary electron to the beam collector appear at two analyzing magnetic field intensities which correspond to two relations of mu^- muon (the mass m_1 = 207 m_e and the charge q_1 = e) and pi^- meson (the mass m_2 = 273 m_e and the charge q2 = e, where m_e and e are mass and charge of electron). We consider that the pi^- meson may be produced by a coherent interaction between the magnetically bunched beam electrons and the electrically bunched beam ions, and that the negative muon mu^- may be produced though the decay of pi^- meson.
