Abstract

We show that the molecular relativistic Thomas-Fermi-Weizsacker functional consisting of atoms of atomic numbersZ(1), horizontal ellipsis ,Z(k)has a minimizer, if the particle numberNis constrained to a number less or equal to the total nuclear chargeZ colon equals Z(1)+ MIDLINE HORIZONTAL ELLIPSIS +Z(K). Moreover, there is no minimizer, if the particle number exceeds 2.56Z. This gives lower and upper bounds on the maximal ionization of heavy atoms.
