Abstract
Measurements of K-shell ionization cross sections of Fe and Mn targets by the impact of electrons of 6 - 25 keV energy have been carried out. In the experiments thin targets with thick aluminium foil substrates were used. The influence on the measurements of electrons reflected from the aluminium substrate has been evaluated and corrected by a detailed electron transport calculation. It is shown that the corrected K-shell ionization cross sections of Mn are in good agreement with existing experimental data. For Mn and Fe, the corrected measured cross sections of K-shell ionization have been compared with the results of the empirical formula given by Casnati et al.Keywords
