Elastic peak

  "id": "MLC-T-CHM-003618",
  "term": "Elastic peak",
  "field": "Chemistry",
  "definition": "A peak in an electron spectrum produced by electrons that were scattered quasi-elastically from the sample, so that they appear at essentially the energy of the primary beam. It is recorded with an electron spectrometer when a solid is bombarded with electrons, as in Auger electron spectroscopy and reflection electron energy loss spectroscopy. The small energy loss from atomic recoil is typically below 1 eV.",
