Abstract
Inelastic collisions of an electron with an atom or molecule, at energies within several eV of an excitation or ionization threshold, lead to the temporary formation of a complex whose available energy is shared in comparable amounts between the incident electron and the one being excited. Analogous complexes are formed when two electrons are excited simultaneously by incident light or by an analogous external agento The properties of such complexes, including the rate and modality of their prompt or delayed decomposition, depend on the correlation of the two excited electrons. Their study — experimental and theoretical, qualitative and quantitative— has yielded considerable understanding. Further development of this understanding and of its quantitative applications constitute, I think, a prerequisite for an adequate, general theory of low energy collision processes.
