Measurement of zinc and manganese K-shell ionization cross-sections by electron impact

This paper provides the experimental measurement of Zn and Mn K-shell ionization cross-sections. The thin targets with thick substrate are used in the experiment. The influence of the reflected electrons from the substrate on the measurements has been corrected by means of a detailed calculation of electron transport. It is shown that the corrected K-shell ionization cross-sections of Mn are in good agreement with the existing experimental data. The paper also presents experimental data of Zn, which are measured for the first time in energy from near threshold to 25 keV.
