摘要: We investigate established theoretical approaches for the determi- nation of electron energy loss spectra (EELS) and inelastic mean free paths (IMFPs) in solids. In particular, we effects alternate descriptions many plasmon resonances that define function (ELF), contribution lifetime broadening these to IMFP. find despite previously claimed agreement between approaches, approximations different models consistently conspire underestimate scattering energies below 100 eV, leading significant overestimates IMFP this regime.
