## Description

- description: We propose an improved method for calculating electron inelastic mean
    free paths (IMFPs) in solids from experimental energy-loss functions (ELFs) based
    on the Mermin dielectric function. The “extended Mermin” method is much simpler
    over a wide energy range than the traditional approach. We employ negative oscillators
    to obtain accurate ELFs; these naturally preserve two important sum rules when
    extending to infinite momentum transfer. Excellent agreement is found between
    calculated IMFPs for Cu and experimental measurements from elastic peak electron
    spectroscopy. Notably improved fits to x-ray absorption fine structure measurements
    of Cu and Mo at low energy illustrate the method’s strength.
