Aug·er e·lec·tron

(awg'ĕr),
an electron ejected from an orbital by photoelectric interaction with a photon emitted when another electron, in a higher energy orbital, passed from a higher to a lower energy level; the Auger electron recoils with energy equal to the characteristic radiation less the difference in shell- binding energies. See: photoelectric effect, transition electron.
