The electron charge density distribution about a zinc solute ion in a dilute aluminum alloy is computed by three different methods. These are: a) an exact method where the solute ion potential is derived from the model potential difference between zinc and aluminum, b) a semiempirical method where the partial wave phase shifts are obtained from alloy specific electrical resistivity, and c) an approximate method where the solute ion potential is represented by a screened Coulomb potential. All three methods are in agreement with the experimentally observed solute ion clustering. Methods a and b also are in agreement with the observed decrease in lattice parameter with increase in zinc content.
