  "id": "MLC-T-CHM-008851",
  "term": "Photoelectric peak",
  "field": "Chemistry",
  "definition": "The peak in a gamma-ray spectrum that corresponds to the full energy deposition of a gamma-ray photon in the detector material. This occurs when the gamma-ray interacts via the photoelectric effect, transferring all its energy to an electron. The energy of this peak directly indicates the energy of the incident gamma ray.",
