Extrinsic plasmon

  "id": "MLC-T-CHM-004313",
  "term": "Extrinsic plasmon",
  "field": "Chemistry",
  "definition": "A plasmon, a quantized collective oscillation of the valence electrons, that is excited by an electron as it travels through a condensed medium after being emitted. In photoelectron and Auger spectra, extrinsic plasmons produce energy-loss satellites on the low kinetic energy side of the main line, and their number follows a Poisson distribution that depends on the path length divided by the inelastic mean free path. Intrinsic plasmons are instead excited by the sudden creation of the core hole.",
