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-.
Note: Penning ionization differs from chemi-ionization in that no chemical change is involved.

Penning ionization

Ionization occurs through the interaction of two or more neutral gaseous species, at least one of which is internally excited.
