The relativistic plane-wave Born-approximation calculations have been performed for K-shell ionization by proton impact. The K-shell ionization cross sections have been obtained by the use of relativistic hydrogenic (Dirac) wave functions for target electrons. The ratio of the relativistic cross section to the nonrelativistic one is evaluated and compared with various approximate correction methods for the electronic relativistic effects. Similar comparison is made for the K-shell ionization cross sections corrected for binding-energy and Coulomb-deflection effects. These results are also compared with the experimental data.
