Abstract

The pseudopotential theory of metals is applied to the Cs–Rb and K–Rb alloy systems using the pseudo alloy atom model. The total binding energies, bulk moduli, and heats of solution were calculated as a function of alloy compositions. The calculated values of the total binding energies showed reasonable agreement with experimental data. The results predict the presence of a mixture of two phases at low temperatures. It is found that previous pseudopotential approaches are justified only for an alloy in which the electron density is nearly uniform. The present model is not subject to such a limitation.
