Examples of the photoelectric effect

When photon energies are as high as the electron rest energy of 511 keV, yet another process,, may occur. Above twice this energy, at 1.022 MeV, is also more likely. Compton scattering and pair production are examples of two other competing mechanisms. Even if the photoelectric effect is the favoured reaction for a particular interaction of a single photon with a bound electron, the resu. [pdf]
