  "id": "MLC-T-CHM-003729",
  "term": "Electron kinetic energy",
  "field": "Chemistry",
  "definition": "The energy an electron possesses due to its motion, calculated as one-half its mass times its velocity squared. In photoelectron spectroscopy, it is the measured kinetic energy of an electron ejected from a sample after absorbing a photon. The binding energy of the electron within the material is determined by subtracting this measured kinetic energy and the spectrometer's work function from the known energy of the incident photon.",
