A gamma ray cross section is a measure of the probability that a gamma ray interacts with matter. The total cross section of gamma ray interactions is composed of several independent processes: photoelectric effect, Compton (incoherent) scattering, electron–positron pair production in the nucleus field and electron–positron pair production in the electron field (triplet production).
