## Description

- description: We have calculated inelastic mean free paths (IMFPs) for 41 elemental
    solids (Li, Be, graphite, diamond, glassy C, Na, Mg, Al, Si, K,Sc,Ti,V,Cr,Fe,Co,Ni,Cu,Ge,Y,Nb,Mo,Ru,Rh,Pd,Ag,In,Sn,Cs,Gd,Tb,Dy,Hf,Ta,W,Re,Os,Ir,Pt,AuandBi)forelectron
    energies from 50 eV to 30 keV. The IMFPs were calculated from experimental optical
    data using the full Penn algorithm for energies up to 300 eV and the simpler single-pole
    approximation for higher energies. The calculated IMFPs could be fitted to a modified
    form of the Bethe equation for inelastic scattering of electrons in matter for
    energies from 50 eV to 30 keV. The average root-mean-square (RMS) deviation in
    these fits was 0.48%. The new IMFPs were also compared with IMFPs from the predictive
    TPP-2M equation; in these comparisons, the average RMS deviation was 12.3% for
    energies between 50 eV and 30 keV. This RMS deviation is almost the same as that
    found previously in a similar comparison for the 50 eV – 2 keV range. Relatively
    large RMS deviations were found for diamond, graphite and cesium. If these three
    elements were excluded in the comparison, the average RMS deviation was 9.2% between
    50 eV and 30 keV. We found satisfactory agreement of our calculated IMFPs with
    IMFPs from recent calculations and from elastic-peak electron-spectroscopy experiments.
