Abstract.
In order to obtain more accurate experimental values of X-ray emission cross sections, resulting from the interaction of ion with atoms, we have measured them for the K-inner-shell of Cr and Cu elements using a proton beam of energy range 1–2.3 MeV. The experimental data obtained in the present work are compared with the theoretical calculations given by the two models BEA (binary encounter approximation) and ECPSSR (energy coulombian perturbed stationary state relativistic). Also, the present experimental results are compared with those obtained by Paul and Sachert. The comparison shows a good agreement between the previous and the present data with a slight improvement in the measurement accuracy for Cr. From the theoretical point of view, agreement with the experimental data is observed only for the ECPSSR predictions, while the BEA’s cross section calculations at higher energies are approximately 20% lower than the present experimental values.
