||Example of collisional process
||Increase of ground state, e.g. suppression of ionization;
Increase in excited state, e.g., ion-electron collisional radiative recombination.
||Depopulation of ground state, e.g. charge transfer reactions;
Depopulation of excited state, e.g., collisional de-excitation
|No effect on signal
||No change in the populations of the ground and excited states of analyte atoms
