A model has been developed for the long-range part of the ion-ion interaction of simple metallic many-particle systems. The investigation is based on the local pseudopotential theory. The essential point in the examination is the consideration of interactions of van der Waals-type in the determination of the direct ion-ion potential and the ion-electron pseudopotential. Numerical calculations performed for liquid rubidium near the melting point show that these interactions are distinctly reflected in the long-range part of the ion-ion potential. The reference potential used in the study had been calculated without parameters by means of the experimentally determined pair correlation function. [ABSTRACT FROM AUTHOR] |
