K-shell x-ray production cross sections for $sup 12$C, $sup 14$N, and $sup 16$O ions on thin targets of Ni, Rb, Ag, and Sb were measured over the incident-ion energy range of 0.4--2.4 MeV/amu. Comparisons to theoretical predictions of the binary-encounter, semiclassical, and plane-wave Born approximations (PWBA) show that these theories overpredict the magnitude of the measured cross sections. The PWBA calculations with perturbation corrections for binding energy and Coulomb deflection effects included are in better agreement with the measured data for E/M < 1.2 MeV/amu. Comparison of the data to the perturbed PWBA calculations which also include corrections of electron polarization effects in the case of $sup 12$C on Ni gives good agreement between these theoretical estimates and the measured K-shell x-ray production cross sections.
