Abstract
The main difference between the scattering by a composite system such as an atom or molecule and by a central field is the possibility of the excitation of the target. Because of this the theory becomes much more complicated even for such a simple system as the hydrogen atom. It seems instructive in many respects to begin with a study of a simplified model of the target which can exist in only two states: the normal or ground state and just one excited state. Correspondingly we will speak about the elastic and inelastic scattering channels. Moreover, we will not take spin into account.
