Abstract: The thermodynamical properties of silver are calculated by using a recent model of many-body potential from lattice inversion method. The predictions of the phonon dispersion relation, the Grüneisen constant and the linear thermal expansion coefficient are all in coincidence with experiments. Of more importance, the present approach represents an efficient way of building potential functions capable of depicting the thermodynamics of metals for the Finnis-Sinclair model.
