Abstract
The experimental measurement of electron-impact K-shell ionization cross sections of Cu and Co elements within the energy region 8–25 keV was reported. The influence of a substrate of thin targets on ionization cross sections has been corrected by a method based upon a bipartition model of electron transport [Z. M. Luo, Phys. Rev. B 32, 812 (1985); 32, 824 (1985)]. The measured cross sections are in good agreement with existing data and are well reproduced by the empirical formula of Green and Cosslett [Proc. Phys. Soc. London 78, 1206 (1961)]. © 1996 The American Physical Society.Keywords
