Abstract:
Free electrons strongly interact with any kind of matter transferring energy and initiating reactions. On one hand they are used in analytical methods and on the other hand they cause intentional and unintentional damages in biological tissue. In this article the basic underlying molecular reactions initiated by electron impact are introduced and some common spectroscopic techniques to analyze and quantify electron collisions are illustrated. Subsequently, some exemplary spectroscopic studies of electron scattering on bio-relevant molecules are discussed. This includes comments on present limitations and future prospects of this technique.
