ABSTRACT
In the nucleonic regime nuclei behave as sets of interacting nucleons. This picture is not only valid in the case of ground-state nuclei but it also holds in the dynamical situations we shall encounter in the following. The standard concepts introduced for describing ground-state properties of nuclei thus constitute, to a large extent and provided with some extensions (which will be discussed in the next chapter), the basic tools needed for understanding nucleonic physics. In this chapter we aim hence at remembering some basic concepts used in the description of ground-state nuclei and, by extension, the nucleonic regime.
