It is the purpose of this article to show in outline how some of the basic ideas of quantum scattering theory can be used to supplement the usual topics covered in elementary quantum chemistry.

Expressions for the time-dependent scattering wave function, S-matrix elements, and the transition rate are derived using simple time-dependent perturbation theory as it is presented in elementary quantum-mechanics texts.

Scattering theory for extended elementary particles in stochastic phase space is studied. It is shown that the interacting Hamiltonian is equivalent to an effective potential in configuration representation. Asymptotic completeness can be studied by investigating the behavior of the effective potential. The sharp-point limit of the extension of these particles is studied. It is also shown that scattering theory can also be studied directly in stochastic phase space in the optimal case.
