Description
We derive a variational characterization for the chemical potential in the Thomas-Fermi model of atoms and molecules. We use this variational principle to obtain accurate upper bounds for the chemical potential ε P (N, Z) as a function of the atomic number Z and the number of electrons N. In particular we study the behaviour of εP(N, Z) for a weakly ionized atom. (author)
