The Auger effect is a physical phenomenon in which the filling of an inner-shell vacancy of an atom is accompanied by the emission of an electron from the same . The Auger effect is a process by which electrons with characteristic energies are ejected from atoms in response to a downward transition by another electron in . The Auger electron is generated during an excited atoms relaxation process, where excess energy is.

Auger-electron definition, a nonradiative process in which an atom in an excited state undergoes a transition to a lower state by the emission of a bound electron . Auger Electron Spectroscopy (Auger spectroscopy or AES) was developed in the late 1960’s , deriving its name from the effect first observed by Pierre Auger, . Both start with an outer electron jumping in to fill the vacancy in the inner shell. Energy is given off as a single X-ray photon. Ionization: A hole in an inner shell (here: K shell) is generated by an incident high-energy electron that loses the corresponding energy E .
