The Coster–Kronig transition is a special case of the Auger process in which the vacancy is filled by an electron from a higher subshell of the same shell. If, in addition, the electron emitted (the "Auger electron") also belongs to the same shell, one calls this a super Coster–Kronig transition.

Additionally, these transitions only occur in solid-state systems and are forbidden for free atoms. This is connected to the fact that the total angular momentum j for a free atom is still a good quantum number.

The Coster–Kronig process is named after the physicists Dirk Coster and Ralph Kronig.
