Abstract : Cross sections are reported for production of positive ions and electrons in collisions of hydrogen atoms in the energy range 1-25 keV with He, Ne, A, Kr, Xe, H2, and O2. Slow, positive ions are produced by capture of an electron by the fast atom from the target gas and by ionization of the target. Electrons are produced by target gas ionization and by stripping of the fast atom. Ionization cross sections for each of the target gases are derived from the positive ion production cross sections and previous measurements of the capture cross sections. (Author)
