Electrical resistivities of liquid Li-Sn and Na-Pb alloys

The resistivity of liquid Li-Sn and Na-Pb alloys is calculated using the theory of ‘‘2 k F ’’ scattering theory recently developed by Morgan et al. The partial structure factors are described by the mean-spherical approximation for a system of hard spheres with Yukawa tails. The calculated resistivity values are in very good agreement with experiment. The improvement over the widely used Faber-Ziman formalism is impressive
