Interatomic Coulombic Decay

In addition to photoemision from an excited atom and the emission of an Auger-electron, Interatomic Coulombis decay provides a third, additional decay mechanism, predicted by Cederbaum et al. In that case the deexcitation energy is transferred to a neighboring atom, which releases it by emission of its most loosely bound electron.
