Abstract
The results of calculations for static structure factors, S(q), and shear v iscosities for less simple liquid metals, Zn, Cd, In, Hg and Pb, are presen ted. These have been studied by using effective interionic pair potentials which are derived from a local approach that successfully combines the sp-b and contribution with the contribution of sd mixing. Specifically the sp-ba nd contribution is described by an empty core model and the d-band contribu tion is deduced from the scattering phase shift by applying an inverse scat tering method. The liquid structure is investigated by using two liquid sta te theories. These are the thermodynamically self consistent variational mo dified hypernetted chain integral equation theory and the linearised versio n of the Weeks-Chandler-Andersen thermodynamic perturbation theory of liqui ds. The viscosity is calculated on the assumption that this property of a l iquid metal resembles that of an appropriate hard sphere liquid. Theoretica l results for both properties are found to be in good agreement with availa ble experimental data. (C) 1999 Elsevier Science B.V. All rights reserved.
