Abstract

Calculations of the resistivity of liquid metals are performed basing on the structure factor a(q) which can be measured experimentally or calculated theoretically from the hard sphere model. The calculations are carried out by using the Ashcroft empty core pseudopotential in the framework of Ziman's formula along with different forms of the screening function due to Hartree, Geldart and Vosko, Hubbard, Overhauser, random phase approximation and self-consistent screening. The investigation is useful because it throws light on the importance of exchange and correlation effects in developing an appropriate description of the screening of ions by conduction electrons for calculating the resistivity of liquid metals.
