This paper presents calculations of electron-loss cross sections for fast H(1{ital s}) projectiles incident on different atomic targets (He, Ne, Ar, Kr, Xe, H, N, or O) for a broad kinetic-energy range (90 keV/amu to 1.4 GeV/amu), and compares the calculations with experimental measurements where possible. The calculations are based on the semiclassical free-collision model. Theoretical differential cross sections for elastic electron scattering, and theoretical or semiempirical differential cross sections for inelastic electron scattering, are used in making the calculations. The results are in good agreement with experimental data. We apply a simple model based on the H(1{ital s}) results to obtain single- and double-electron-loss cross sections for H{sup {minus}} projectiles incident on the same atomic targets. Again the results are in good agreement with experiment. Further calculations have yielded results for electron loss of H(1{ital s}) incident on molecular H{sub 2}, N{sub 2}, and O{sub 2} targets.
