Investigation of the interatomic interaction and structure in liquid metals by the pseudopotential method

The calculation of the interatomic interaction by the pseudopotential method with different models for the form factors has been considered, and the effect of the kind of screening of the electron gas on the form of the potential has been investigated. The potentials of the pair interaction which were calculated have been used to solve the Bogolyubov-Born-Green and the Percus-Yevick integral equations for the radial distribution function. Questions about the applicability of this method for computing the structure and thermodynamic properties of liquid metals are discussed.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 11, pp. 44–49, November, 1979.
