Numerical values are given for the photon differential and total cross sections, the electron scattering angle and the electron kinetic energy. The directions of the scattered photons are shown by a dashed red arrow, while the scattered electron (initially at rest) follows the dashed blue arrow. The Compton effect is a partial absorption process and as the original photon has lost energy, known as Compton shift (i.e. The cross-section is expressed in units of, with a maximum value of, as shown by the light red circle. Compton effect Data Graphing 1 danny20051 13 0 Homework Statement Not sure whether I should be posting this here or in the quantum physics thread but I felt this more of a homework question. THE COMPTON EFFECT Group Name : Red Devils Member Name & ID Nusrat Isalm Setu -182-47-736 Md. Compton scattering is usually described two Feynman graphs (in the second-order perturbative expansion of scattering matrix) that can be described in the following way: annihilation of a photon-electron pair, propagation of a virtual electron, creation of a photon-electron pair (a) exchange graph. A polar plot of the differential scattering cross section is shown in the graphic, with photon energy selectable in the range 0–10 MeV.
The formulas pertain to the average of the two photon polarizations. Klein and Nishina (1929) derived the scattering cross-section according to Dirac's relativistic theory of the electron:, where and, the incident photon energy in units of the electron rest energy (511 KeV/ ). During the study, Compton found that wavelength is not dependent on the intensity of incident radiation. Arthur Compton studied this effect in the year 1922. The Thomson formula is, however, inadequate to treat the higher-energy photoelectric and Compton effects. The Compton effect illustrates one of the most fundamental interactions between radiation and matter and displays in a very graphic way the true quantum nature of electromagnetic radiation. The Compton effect is defined as the effect that is observed when x-rays or gamma rays are scattered on a material with an increase in wavelength. The photon interaction process: Photoelectric effect, Compton and Rayleigh scattering, Pair production Home Blog By Stefano Meroli The behavior of photons in matter is completely different from that of charged particles. The corresponding total scattering cross-section is given by. This separation $\Delta \lambda $ is called the Compton shift.Low-energy (Thomson) scattering of a photon by an electron is approximated by the differential scattering cross section, where, the classical electron radius.

The two peaks are separated by $\Delta \lambda $, which directly depends on the scattering angle $\theta $ of the scattered beam. Explore math with our beautiful, free online graphing calculator. Here, $\lambda $ is the wavelength of the original photon and $$ ,which is the wavelength of the scattered photon.
