Thermodynamics and structure of liquid binary alloys calculated using an analytic pair potential

Analytic pair potentials proposed by Pettifor and Ward are developed using the Heine-Abarenkov pseudopotential for Lidnarrowa, Na--K, and Na--Cs liquid binary alloys. The corresponding partial structure factors are calculated using the random-phase approximation. The calculated thermodynamic and structural properties using this real-space formalism are in good agreement with experiments.
