Abstract
Inelastic scattering is characterized by a change in the internal state of one or both collision partners, but with no change in their chemical identities. Thus electronic, vibrational, and rotational excitation and de-excitation are inelastic events, whereas chemical reactions, charge transfer, ionization, and dissociation would be characterized as reactive events. One may also include collisions which change the orientations of the partners (Δm ǂ 0), but do not change the energy state. In the following section and the next three chapters the theory of inelastic collisions of various types is given in considerable detail. In this section we shall define the relations between observables and the theoretical quantities, outline the general quantum theory of such processes and three practical (for small systems) quantum approaches, and give a brief overview of some of the alternative approximate approaches which are given in greater detail in later chapters. There are, of course, many reviews and books covering inelastic scattering; some are given in References 1–7.
