Penning ionization |
---|
Ionization via electron removal that occurs through the energy transfer from a neutral species (N) internally excited to a metastable state (such as a high Rydberg state) to a neutral species (M) with lower ionization energy, as represented by the following reaction: N* + M → N + M+• + e-.
