WebDec 14, 2024 · Cross-Sections of Photoelectric Effect. At small values of gamma ray energy the photoelectric effect dominates. The mechanism is also enhaced for materials of high … 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. tips van thijs sharepoint
