We present a well-defined path integral for scattering theory. This path integral is particularly well suited for evaluating the semiclassical expansion for the cross section. As an example, we show how the semiclassical cross section for rainbow scattering can be obtained in a systematic fashion. We indicate how the path-integral approach to semiclassical scattering theory may be more general and more reliable than other approaches.
