Photoelectric effect and compton scattering
Webσ f – Photoelectric effect; σ C – Compton scattering; σ p – Pair production; One of the three partial cross-sections may become much larger than the other two depending on the gamma-ray energy and the absorber material. At small values of gamma-ray energy, the photoelectric effect dominates. Compton scattering dominates at intermediate ...

WebAug 1, 2024 · This plot is for the interaction of photons with electrons in copper. At low energies, the photoelectric effect is the dominant effect. From about 200 keV to about 10 MeV, Compton scattering is the dominant effect. Above 10 MeV, the dominant effect is pair production. At a given photon energy, the relative probability of two processes would be ... WebCompton scattering, which views the photon–electron scattering to behave rather like billiard balls colliding with other billiard balls, thus reinforces Einstein’s explanation of the photoelectric effect. An outline of this article is as follows. Section 2 gives an overview of the theory of Compton scattering.

Photoelectric effect Compton scattering Compton scattering is an example of inelastic scattering. The incident photon loses energy in the lab frame, which centuries of practice had identified with inelastic scattering—even though, in the c.m. frame, the respective masses remaining the same, no new species are created and kinetic energy is conserved, the mark of an elastic collision. As a result, HEP and nuclear physic…
