Abstract
The K-shell X-rays and elastic scattering particles induced by 3.0–15 MeV oxygen ions were measured simultaneously for selected elements between Ti and In (in the atomic number range Z = 22–49). Experimental K X-ray production cross sections as a function of projectile energy in this energy interval in steps of 0.6 MeV are reported. Results of measurement are compared with the predictions of the first Born, the ECPSSR and the MO ionization theories. The first Born and the ECPSSR theories give about the same trends of energy dependence of cross sections. However, the first Born approximation overestimates the experimental data by about a factor of 20 throughout the investigated energy range. The ECPSSR prediction shows a better agreement with the experiment, except at lower energies, where the MO theory matches the data slightly closer.
