The total ionization cross section and spin asymmetry at projectile energies ranging from threshold to 500 eV for electron impact excitation of atomic hydrogen is presented. They are calculated using the convergent close-coupling formalism of Bray and Stelbovics. Both observables are found to be in complete quantitative agreement with measurements over almost the entire energy range. This is the only electron-atom scattering theory that is able to achieve this result to date. 20 refs., 2 figs.
