Following the pioneering work of Thomas (1926) and Fermi (1928), in which the electronic properties of heavy atoms were described by the electron density, two parallel descriptions of electron states have been employed:.(i) Using one-body wave functions ., the Hartree and Hartree

Our task is made easier by the excellent lectures on the fundamental theory given by Professor March and other participants of this school. Let us begin by remembering the connection between the basic N-electron quantum state . and

The scattered wave results from the interaction of these two and it may be better to consider scattering simply as the response of a radiation field to a non-uniform potential.
