## Title

    solids over the 50-2000 eV range

## Description

- description: We report calculations of electron inelastic mean free paths (IMFPs)
    for 50 eV to 2000 eV electrons in 14 elemental solids (Li, Be, diamond, graphite,
    Na, K, Sc, Ge, In, Sn, Cs, Gd, Tb, and Dy) and for one solid (Al) using better
    optical data than in our previous work. The new IMFPs have also been used to test
    our TPP-2M equation for estimating IMFPs in these materials. We found surprisingly
    large root-mean-square deviations (from 39.3 % to 71.8 %) between IMFPs calculated
    from TPP-2M and those calculated here from optical data for diamond, graphite,
    and cesium. An analysis showed that these deviations occurred for relatively small
    computed values of the parameter beta in the TPP-2M equation (beta ~ 0.01 for
    diamond and graphite) and for a relatively large value of beta (beta ~ 0.25 for
    Cs). While such extreme values of beta are unlikely to be encountered for many
    other materials, the present results indicate an aditional limitation in the reliability
    of the TPP-2M equation. We also show that the parameter Nv in the TPP-2M equation
    should be computed for the rare-earth elements from the number of valence electrons
    and the six 5p electrons.
