摘要
Elastic peak electron spectroscopy (EPES) is used for determination of inelastic mean free paths in silver and copper for electrons with energy of 250, 500, 1000 and 1500 ev. Namely, the elastic scattering coefficient eta //e is measured with a retarding field analyzer (LEED optics) and calculated by computer simulation for different values of the inelastic mean free path lambda . A value of lambda giving the best fit for the measured and calculated eta //e is taken as the experimental inelastic mean free path. Results obtained are in agreement with those known for the literature. Equivalency between the values of eta //e obtained by analytic calculation and by computer simulation is found.
