  "id": "MLC-T-CHM-012755",
  "term": "X-ray emission spectrum",
  "field": "Chemistry",
  "definition": "The distribution of X-ray photon intensities as a function of energy or wavelength, emitted by a substance when its inner-shell electrons are excited and subsequently relax. It consists of characteristic lines corresponding to specific electronic transitions and a continuous bremsstrahlung background. The characteristic lines are unique to each element and are used for elemental analysis.",
