Abstract
The absorption of elastic flux for electrons with energies in the range 0-20 Hartrees (0-500 eV), interacting with tightly bound bands in a crystal. The inelastic scattering is usually dominated by conduction and valence bands and varies with energy in a manner substantially independent of the band being excited, asymptotically as E-12/lnE. In close-packed structures the strength of absorption varies only weakly over the unit cell, but for more open structures large variations can be expected from one part of the cell to another. The results are relevant to LEED and photoemission experiments.Keywords
