09326 IUPAC Gold Book - electron energy loss spectrum 10.1351/goldbook.09326 09326 current 1 Energy spectrum of electrons from a nominally monoenergetic source emitted after inelastic interactions with the sample, often exhibiting peaks due to specific inelastic loss processes (see characteristic electron energy losses and plasmon). The electron energy loss spectrum obtained using an incident-electron beam of about the same energy as a peak obtained in Auger electron spectroscopy or X-ray photoelectron spectroscopy approximates to the energy loss spectrum associated with that peak. The electron energy loss spectrum, measured with an incident-electron beam, is a function of beam energy, angle of incidence of the beam, angle of emission, and the electronic properties of the sample.
