Effective thermal cross-section

{
  "id": "MLC-T-CHM-003594",
  "term": "Effective thermal cross-section",
  "field": "Chemistry",
  "definition": "A measure of the probability that a thermal neutron will induce a specific nuclear reaction in a target nucleus. It represents the apparent area presented by a nucleus to an incident thermal neutron for a particular interaction. This value is typically expressed in barns (1 barn = 10^-28 m^2).",
