Siedentop, Heinz K. H.; Weikard, Rudi On some basic properties of density functionals for angular momentum channels. (English) Zbl 0644.46059 Rep. Math. Phys. 24, No. 2, 193-218 (1986). Summary: We investigate some basic properties of the Hellmann and the Hellmann- Weizsäcker energy functional, density functionals, which use densities for angular momentum channels as trial functions, and investigate their relation to the ground state energy of an atomic N-electron system. Furthermore, various scaling properties are shown, the virial theorem, and in the case of no electron-electron interaction the dependence on the nuclear charge.
