  "id": "MLC-T-CHM-008115",
  "term": "Nuclear reaction cross section",
  "field": "Chemistry",
  "definition": "A measure of the probability that a specific nuclear reaction will occur when a projectile particle interacts with a target nucleus. It represents an effective area that the target nucleus presents to the incident particle for a particular reaction. This quantity is typically expressed in units of barns (b), where 1 barn equals 10^-28 square meters.",
