WebMar 6, 2016 · Complete absorption of the incoming x-ray photon occurs when it has enough energy to remove (eject) an inner-shell electron. The ejected electron is called a photoelectron and quickly loses energy by interacting with nearby tissues. The ability to remove (eject) electrons, known as ionization, is one of the characteristics of x-rays. simplify fully 50 55

WebThe photoelectric effect is a common interaction between a low-energy photon and a material. In this process the photon interacts with an electron in the material losing all of its energy. The electron is ejected with an energy equal to the initial photon energy minus the binding energy of the electron.

WebWe will call this last energy the electron-metal binding energy. As an equation we write write: E incoming photon =KE electron +E electron-metal binding. Equivalently: (Kinetic Energy) max for electron = E photon-E electon-metal binding. This equation tells us that increasing the incident photons energy will increase the Kinetic Energy of the ...
