Measurements of K-vacancy production cross sections are reported for 0.5- to 3.5-MeV/amu H, He, O, F, and Cl bombardments of selected elements between Y and U. Ratios of H- to He-induced cross sections corrected for binding effects are compared with proposed Coulomb-deflection correction factors. The validity of the Kocbach factor is confirmed. Ratios of experimental H- and He-induced cross sections to plane-wave Born-approximation cross sections, corrected for binding and Coulomb-deflection effects, agree with theoretical relativistic correction factors calculated in the preceding paper. A new semiempirical formula for predicting 1ssigma-vacancy production cross sections is derived. The overall agreement of the new formula with H-, He-, O-, F-, Cl-, Kr-, and Xe-induced cross sections is generally within experimental uncertainties (10%-20%).
