Description

Compton scattering is an interaction of photons with atomic electrons, in which both the energy and the momentum are conserved. The photon interacts with a constant interaction cross section per electron eσc for all materials at a certain photon energy. However the Compton scattering cross section per atom, σc, is equal to the number of electrons in the atom multiplied by the eσc [1]: σc=Zeσc this characteristic means that for a given photon energy, each material has a unique scattering cross section different from other materials. It also means that the higher the atomic number, the stronger the signal obtained from Compton scattering, at least for small thicknesses.
