The interaction of 800-MeV ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$ ions with a thin foil produces protons, the ground state and excited states of neutral ${\mathrm{H}}^{0}$ atoms, and unstripped ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$ ions. We inve

Resonance line narrowing up to 1/2 of the natural linewidth has been observed for microwave magnetic-resonance transitions between Zeeman levels of ground-state muonium at a strong magnetic field of 1.7 T. The observed lines are in good agreement wit

The space charge code SCHAR has been used to interpret some of the measurements made with the LAMPF ECR (Los Alamos Meson Physics Facility electron cyclotron resonance) source. Calculations were made for rectangular hole (ribbon beam), single hole, a

Foil stripping of H/sup -/ directly to H/sup +/ is being considered for proton injection in the next generation of high-current proton storage rings. This technique can result in significant losses because excited states of H/sup 0/, which are also p
