Introduction to (multiple) scattering theory
Abstract
In this introductory chapter, we develop the scattering theory necessary to understand the theoretical models underlying the multiple scattering codes. First, the elementary theory is presented and it is then formalized to introduce the different operators whose matrix elements are computed in the codes. Then, we extend the theory to the case of a collection of potentials, i.e. multiple scattering. Finally we outline the way cross-sections can be derived from the multiple scattering framework and give some practical examples. © 2018, Springer International Publishing AG, part of Springer Nature.
