摘要

After a short discussion on the extraction of pair potentials from measurements of liquid structure, with the example of liquid Na near its freezing point, some examples of liquid metals under a wide range of thermodynamic conditions are considered. In particular, expanded fluid Cs and liquid H and D are referred to. The nuclear structure factor S(k) is then considered in relation to its electronic correlation functions in liquid metals under conditions where a sharp separation can be made into core and valence electrons. Results on the valence electron-ion correlation function for liquid Mg and liquid pi are reviewed and possibilities for seeing valence-valence electron pair correlations are mentioned. Electrical resistivity theory is then treated in terms of a force-force correlation function, and the weak electron-ion interaction is found to be a limiting case, leading to the Bhatia-Krishnan-Ziman formula. However, for expanded Cs, one-body potential theory needs transcending and in doing so an inter-relationship between electrical resistivity and magnetic susceptibility is exposed, Some directions for future work are finally suggested.
