Dielectric recombination
The dielectronic recombination is a physical process in which an electron is trapped by a positively charged ion. Another electron of the ion is excited.
A positively charged ion can become doubly excited by trapping an electron . This state can decay into its original state through autoionization or into a stable state through the emission of a photon . The latter is called dielectric recombination. It can only take place if a resonance condition is met. The energy released when the electron is captured must correspond to the excitation energy of the transition of the second electron.
