3 The Nucleon-Nucleon Interaction

3.1 Introduction

The starting point for any dynamical description of a physical system is knowledge of the relevant degrees of freedom and of the interaction. In the previous chapters we have seen that nucleons are the basic components of nuclei. Their degrees of freedom are determined by the position ri, momentum pi, spin si and isospin τi of the ith nucleon. For the interaction one first takes the simplest assumption that it is a two-body interaction that can be described by a potential. A further extension of the model introduces three-and many-body interactions for a deeper understanding of the many-body system. For historical reasons we will first give with a phenomenological description and later the more ...
