On the Green's Function of Potential Scattering.
Abstract
The Green's function in some potential scattering problems of spherical symmetry is written as an integral of the product of the Green's function Ga corresponding to the angular variables and Gr corresponding to the radial variables. The integration is carried along a suitable line C in the plane of complex anguar momentum. If c surrounds the spectrum of Ga the usual partial waves expansion is obtained, if C surrounds the spectrum of Gr a different expansion reults which is the most suitable for describing collisions involving small wave lengths.
