Temperature dependence of atomic transport in less-simple liquid metals

We report on the atomic transport properties viz. the coefficients of shear viscosity and self-diffusion for certain less-simple liquid metals at various temperatures. The basic assumption made is that these properties of a liquid metal resemble those of an appropriate hard-sphere system. The temperature dependence of the basic ingredients, i.e., the hard-sphere diameters and packing fraction, is considered via a full thermodynamic perturbation theory. The optimal values of these basic ingredients are employed in calculating the atomic transport coefficients of Cu, Cd, ln, and Pb. The calculated results are found to be in good agreement with the experimental and available theoretical results.
