A model potential approach fs considered for electron-and positron-atom scattering in order to handle with ease the calculation of the scattering amplitudes in the case of collision by a more complex atomic target. As an illustrative example demonstrating the feasibility of this method of approach,
The usual textbook one-particle Green's function possesses a self-energy that is known to be an optical potential for elastic scattering. The introduction of an optical potential reduces the complex many-body scattering problem into a tractable one-body problem. In this work the definition of Green'
