Exact second order theories for electron-atom scattering
Abstract
Second order effects are known to be important in several areas of atomic physics. In spite of the importance of second order effects, most second order calculations have resorted to simplifying approximations of questionable validity. We have recently developed the capability for evaluating arbitrary second order amplitudes exactly for elastic scattering and atomic excitation by electron impact. With this capability one can evaluate second order distorted wave amplitudes for arbitrary distorting potentials and arbitrary distorted Green's functions in the interaction operator. In this paper, we will first discuss the various types of possible second order amplitudes and then we will give an overview of our results for the excitation of hydrogen by electron impact.
