Abstract The reference level of the separated constituents and the crossing of the potential curves for the ionic and covalent state are discussed with respect to the choice of orbital occupation numbers and Fermi-Dirac statistics. Calculations show a distinct crossing of potentials curves, when using a constraint of integer occupation numbers. No crossing is predicted, when fractional occuption numbers are used, which are adjusted according to Fermi-Dirac statistics.[/p]
