Usually, the cross section of the photoeffect can be approximated by the simplified equation of The photoelectric effect is the dominant energy transfer mechanism for X-ray and gamma ray photons with energies below 50 keV, but it is much less important at higher energies, but still need to be taken into consideration. This results the ejection of that electron from the atom. This phenomenon describes the situation in which a gamma photon interacts with an electron located in the atomic structure. The detailed equations for cross sections ( barn/atom) of all mentioned effects connected with gamma ray interaction with matter are listed below. Other effects, like the photonuclear absorption, Thomson or Rayleigh (coherent) scattering can be omitted because of their nonsignificant contribution in the gamma ray range of energies. The cross section for single process listed above is a part of the total gamma ray cross section. The total cross section of gamma ray interactions is composed of several independent processes: photoelectric effect, Compton scattering, electron-positron pair production in the nucleus field and electron-positron pair production in the electron field (triplet production). ![]() Gamma ray cross section - a measure of the probability that gamma ray interacts with matter.
