Calculation of energy spectra of electrons transmitted through thin aluminium foils

The use of an analytical formula for the energy loss spectrum of plasmon, single-electron and inner-shell excitation of aluminium in the Landau theory of multiple scattering results in a better agreement with experimental values of the mean energy loss and the half width of the energy distribution of 10-100 keV electrons transmitted through aluminium foils than the original Landau theory. The same loss spectrum can be used in Monte Carlo calculations instead of a Bethe continuous slowing down approximation for a better consideration of plasmon losses and straggling and for calculating multiple scattering effects in electron energy loss spectroscopy (EELS).
