When an inner electron is removed from an atom in a photoelectric interaction, thus
causing an inner-shell vacancy, the energy liberated when this vacancy is filled can be
transferred to another electron of the atom, thereby ejecting that electron, instead of
emerging from the atom as characteristic radiation. What is this electron called?
, Auger electron
Compton electron
Edison electron
Sievert electron

Auger electron
