WebThe Compton eﬀect is the elastic scattering of photons from electrons. As a reaction, the process is: γ +e −→ γ +e . Since this is a two body elastic scattering process, the angle of … WebWhen a photon interacts with an atom, a number of different absorption and scattering processes may occur. For an isolated atom at photon energies of less than 100 keV (the limit of most conventional X-ray generators), contributions to the total cross section come from the photo-effect, coherent (Rayleigh) scattering, and incoherent (Compton) scattering.
