  "id": "MLC-T-CHM-000178",
  "term": "Activation cross-section",
  "field": "Chemistry",
  "definition": "A measure of the probability that a nuclear reaction will occur when a target nucleus is bombarded by a particle. It quantifies the effective area presented by the nucleus for a specific reaction. This value is expressed in units of area, typically barns (b), where 1 barn equals 10^-24 cm^2.",
