WebThis process reduces the energy of the photoelectron slightly (∼10–40 eV), and the energy difference can either be absorbed by the atom or added to the energy of the Auger electron. At the end, the atom becomes doubly ionized. Case b: Photoemission accompanied by a shake-off event WebIf the photons are high enough in energy electrons are promoted to such high energies that they are ionized they come off the atom completely. This phenomenon is called the photoelectric effect, and is shown in the figure below. This technique is used in photocells and other electronic devices.
