TLDR
In this article, the energy loss per unit path length and inelastic mean free path of an electron with energy less than or equal to 10 keV are modified by including an exchange correction, a sum-rule constraint, and a small relativistic correction.Abstract:
Previous results for the energy loss per unit path length and inelastic mean free path of an electron with energy less than or equal to 10 keV are modified by including an exchange correction, a sum-rule constraint, and a small relativistic correction. These new results are compared with the previous results, tabulated values, and predictions from ''universal'' formulae for organic solids.read more

Optical properties of polyethylene: measurement and applications
TL;DR: In this paper, the optical properties of polyethylene, obtained from transmission measurements on thin films, are presented for photon energies from 0.5 to 76 eV, and the results for the extinction coefficient are combined with calculated values in the soft and hard X-ray regions, and both their internal consistency and their consistency with data obtained previously for polystyrene are verified through a sum rule calculation.
