Investigations of the static and dynamic properties of liquid less simple metals

Abstract

Static structure factors, S(q), thermodynamic properties and shear viscosities for liquid Zn, Cd, Hg, In, Tl, Sn, Pb, Sh, and Bi are investigated systematically. A model pseudotential which combines the sp- and d-band contributions is employed to derive interionic interactions. The liquid state is described by using the thermodynamically self-consistent variational modified hypernetted chain (VMHNC) integral equation theory, and also by using the linearised version of the Weeks-Chandler-Andersen (LWCA) thermodynamic perturbation theory of liquids. Results of calculations for all of the above properties are found to be in good agreement with available experimental data. The calculated results also reveal qualitatively that there is a relationship between the rate of change of viscosity with temperature and the depth of the potential well concerned.
