Abstract
-shell x-ray production cross sections for thin targets of selected elements Ti to Sb have been measured for ions in energy steps of 0.2 MeV/amu in the range from 1.0 to 5.0 MeV/amu. Comparisons of the cross-section data for the lighter elements () to the plane-wave Born approximation (PWBA) and the PWBA corrected for binding energy and Coulomb deflection show that the data are best represented at the lower energies by the corrected PWBA and approach the PWBA at the higher energies. When approximate relativistic corrections are made to the theories for the heavier elements studied, the same general trend is observed. Calculation of the ratio supports the inclusion of binding energy and Coulomb defection corrections to the PWBA at the lower ion energies. The corrections to the PWBA, while improving the fit to the data, underestimate the cross sections by 10-100% in all cases. The ratios are found to be in good agreement with theoretical estimates assuming single-hole ionization.
