TLDR
In this article, a comparison between electron inelastic mean free path and attenuation length was made using the partial wave expansion method with a solid potential to evaluate the path length distribution of an electron transmitted through a solid film.Abstract:
The electron inelastic mean free path is of basic importance in theoretical and applied radiation physics and surface physics. It can be calculated using the dielectric function for the valence band and atomic generalized oscillator strengths for inner shells of a solid. Although the experimentally determined attenuation length is conceptually different from the theoretically calculated mean free path, they are frequently used interchangeably in a loosely defined manner. For electrons with energies below a few keV, elastic scattering plays an important role in connecting these two quantities. This work employed elastic scattering cross sections derived using the partial wave expansion method with a solid potential to evaluate the path length distribution of an electron transmitted through a solid film. Both the analytical multiple-scattering formulation and the numerical Monte Carlo simulation have been applied in this investigation. A comparison between electron inelastic mean free paths and attenuation lengths was made.read more

Electron inelastic mean free paths for plasmon excitations and interband transitions
TL;DR: In this article, an extended Drude dielectric function was established to describe the response of valence bands to fast electrons in solids of complex band structures, and the real and imaginary parts of the function were checked with experimental data to confirm critical point energies in the interband transitions and plasmon energies in collective excitations.

TL;DR: In this article, the authors describe the behavior of simple metals, rather than the complicated metals, such as the transition metals and the rare earths, and discuss the applications of such simple metals.
