Photoelectron X-ray satellite peaks

{
  "id": "MLC-T-CHM-008861",
  "term": "Photoelectron X-ray satellite peaks",
  "field": "Chemistry",
  "definition": "Weak photoelectron peaks in an XPS spectrum produced when minor characteristic lines of the X-ray anode, such as the Kalpha3 and Kalpha4 lines of a magnesium or aluminium source, also excite photoemission. Each main peak is therefore accompanied by small replicas roughly 8 to 12 eV lower in binding energy. A monochromator removes them.",
