A possibility of π- meson production by a low energy electron bunch and positive ion bunch

A low energy electron beam (≤ 1200 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 μ- muon (the mass m1 = 207 me and the charge q1 = e) and π- meson (the mass m2 = 273 me and the charge q2 = e, where me and e are mass and charge of electron). We consider that the π- 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 μ- may be produced through the decay of π- meson.
