activation cross section
Activation cross section is a measure of the probability of the occurrence of a nuclear reaction. The cross section is the apparent surface which a target nucleus exposes to an arriving particle. The cross section is indicated in surface units. Neutron cross sections are frequently measured in units called barns, symbol: b. 1 barn is equal to 10-28 m2.
