 ABSTRACT: 

The adiabatic connection procedure of density functional theory hasbeen applied to two- and four-electron atomic systems by following a nonlinear paththat leads from the noninteracting Kohn–Sham reference system to the physical one. Wehave calculated the exchange and correlation energies as the interaction strength isincreased, as well as the densities of the corresponding correlation holes.
