The Transport Coefficient for Non-transition Elements

Using the recent experimental data for liquid aluminum, copper, lead, tin, gallium and bismuth, the effective interatomic potential has been calculated by inverting the Week-Chandler-Anderson (WCA) perturbation theory.Also, first and second derivatives of interatomic potential y(r), along with different correlation functions as g(r), c(r), have been calculated for the mentioned liquid metals. With knowledge of the above quantities and their products, different transport coefficients, such as self-diffusion D, viscosity r7 and conductivity &have been studied, for the group of transition and nontransition elements, and their results compared with classical measurements of the macroscopic quantities. Our aim in this work was to study the transport processes in the transition and non-transition elements from the aspects of their microscopic static properties. The transport coefficients D can be defined in terms of the intermolecular forces through the relations of Rice and Kirkwood /1-3/, . . Here \Q ( r ) and ( r ) denote the derivatives of the effective pair potential '4 ( r ) , g ( r ) , m, n a r e respectively the pair correlation function, mass and density of the system. In a similar manner the shear viscosity coefficient , the bulk viscosity 2, and the coefficient of the conductivity a' can be expressed
