Calculations are reported of inelastic mean free paths (IMFPs) for 100–2000 eV electrons in C, Mg, Al, Al2O3, Cu, Ag, Au, and Bi from experimental optical data. These calculations require knowledge of the momentum-transfer dependence of the differential scattering cross section; this information was taken from Penn's calculations. The calculated IMFPs agree reasonably with direct calculations and with measured electron attenuation lengths (ALs). Since accurate measurements of ALs are difficult… CONTINUE READING
