WebCompton effect, also called Compton scattering, increase in wavelength of X-rays and other energetic electromagnetic radiations that have been elastically scattered by electrons; it is a principal way in which radiant energy is absorbed in matter. The effect has proved to be one of the cornerstones of quantum mechanics, which accounts for both wave and particle … WebJul 1, 2012 · The photoelectric effect requires the interaction of the WHOLE SOLID. In effect, the whole solid absorbed the energy and "promotes" the electron into the vacuum state. The Compton scattering is the interaction with the electron itself, and doesn't require either the whole solid or the atom be a part of the interaction.

WebThus, in lead, interaction below 0.1 MeV is almost exclusively photoelectric; between 0.1 MeV and 2.5 MeV both photoelectric and Compton processes occur; and between 2.5 MeV and 100 MeV Compton scattering and pair production share the interaction.
