IMPORTANT PRELIMINARIES ON ATOMS
Electronic structure of atoms
This chapter is concerned with the issues of solving the self-consistent Kohn-Sham and Hartree−Fock equations in the simplest geometry. We will not be concerned with the intricate details of the states of many-electron atoms, but only those aspects relevant to our primary goal, the electronic structure of condensed matter and molecules. Studies of the atom illustrate the concepts and are directly relevant for following sections since they are the basis for construction ...
