Measurement and Multiple Scattering Correction of K-ShellIonization Cross Sections of Silver by Electron Impact

The K-Shell ionization cross sections of silver have been measured by electron impact. In order to overcome the difficulties in preparing a self-supporting thin target, a thin target with a thick substrate was used in our experiments. The influence of electrons reflected from the substrate was corrected by means of a detailed calculation of electron transport. The path of the electrons passing through silver target of 31.2μg/cm² was calculated by the EGS4 Monte Carlo program. This method of correction for the measurement is reported for the first time.
