Measurement of 8~25 keV electron impact K-shell ionization cross sections of Cu and Co elements

Measurement of 8~25 keV electron impact K-shell ionization cross sections of Cu and Co elements 1 first-author 1 1 1 Institute of Nuclear Science and Technology, Sichuan Union University, Chengdu 610064 Institute of Nuclear Science and Technology, Sichuan Union University, Chengdu 610064 The influence of substrate of thin targets on ionization cross sections has been corrected by a new method based upon the bipartition model of electron transport. The measured cross sections for Cu element are in good agreement with existing experimental data and those produced by the empirical formula of Green and Cosslett. Cross sections for Co element are measured for the first time. K -shell ionization cross section Electron impact Thin target with thick substrate Electron transport References Powell C J .
