The term generally used to describe @I03183@ of any species by photons. The process may, for example, be written
P04620.png
Electrons and photons do not 'impact' molecules or atoms; they interact with them in ways that result in various electronic excitations including @I03183@. For this reason it is recommended that in @M03746@ the terms 'electron impact' and 'photon impact' not be used.Sources:
