Calculation of the electrical resistivity of liquid rate earths. I. The divalent elements Eu, Yb

Abstract
The electrical resistivities rho of liquid Eu and Yb are evaluated in the framework of a single-site matrix approach. The Fermi energy EF and the diameter 2kF of the Fermi sphere are determined by a simple approximation to the density of states and the relation kF2=2mEF. Using structure factors measured by Waseda (1977) for two different temperatures we also calculate the temperature coefficient of rho . The agreement with experiment is quite satisfactory.
