Total cross sections of proton-impact ionization of the hydrogen atom are calculated with recoil effects in the relativistic two-potential formalism from 0.1 to 2000 keV incident energies. The distorting screened-potentials of final states are used to mock the time-average positions of proton, electron, and target nucleus, while correlations between three reaction products are treated with residual potentials. Comparison with experimental results demonstrates that the mechanism of saddle-point electrons, in the broad sense, gives rise to less than 10% of the ejected electrons with incident energies less than 0.3 keV, and more than 90% of the ejected electrons above 10 keV.
