Abstract

The first observation of muonium (+e-) in vacuum, produced when a low-energy positive muon beam impinges on a thin foil target, is reported. It is found that +e- emerges from the foil surface predominantly with energies of less than 20 keV. The results show that the Clinton P. Anderson Meson Physics Facility stopped-muon channel operating at E=4.0 MeV with an average flux of 3×106+/s can produce roughly 103+e-/s in vacuum from thin targets of Be, C, Al, Cu, Ag, and Au.
