Abstract
-shell x-ray production corss sections for , , and 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 MeV/amu. Comparison of the data to the perturbed PWBA calculations which also include corrections of electron polarization effects in the case of on Ni gives good agreement between these theoretical estimates and the measured -shell x-ray production cross sections.
