International audienceWe show how every bound state of a finite system of identical fermions, whether a ground state or an excited one, defines a density functional.Degeneracies created by a symmetry group can be trivially lifted by a pseudo-Zeeman effect. When complex scaling can be used to regularize aresonance into a square integrable state, a DF also exists
