This phenomenon describes the situation in which a gamma photon interacts with an electron located in the atomic structure. This results the ejection of that electron from the atom. 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. WebMar 29, 2024 · Note that this is a log-log plot! For Carbon, Compton scattering is dominant for photon energies between about 100KeV and 10 MeV while for Lead the photo electric process dominates up to about …
WebThe formula gives the probability of scattering a photon into the solid angle element dΩ = 2π sin Θ dΘ when the incident energy is E0. We illustrate this angular dependence in Figure 2 for three energies of photons, where the vertical scale is given in units of cm2. Fig. 2: Differential Cross-section of Compton scattering vs. angle WebThis section deals with the manner in which the photon scattering and absorption cross sections of an atom varies with the energy of the incident photon. Further information concerning these cross sections and tables of the X-ray attenuation coefficients are given in Section 4.2.4.Information concerning the anomalous-dispersion corrections is given in …
