A transition filling an inner atomic vacancy can transfer its released energy to another bound electron, ejecting it instead of emitting a photon. This provides an atomic relaxation channel following electron capture and ionization.
An electron ejected by the Auger effect. Its kinetic energy is determined mainly by the atomic levels involved, rather than directly by the energy of the radiation that created the original vacancy.

The Auger effect is a physical phenomenon observed in atomic and solid-state physics, where an atom or molecule releases energy in the form of Auger electrons. This effect occurs following the ionization of an atom, typically after the ejection of an inner-shell electron due to high-energy processes such as X-ray absorption or electron bombardment.
