Abstract

We use recently proposed potential to calculate internal energy(enthalpy), entropy and Helmholtz free energy of liquid d- andf-shell metals with the variational approach. The parameter ofthe potential is determined with the standard zero pressure conditionalong with well established Taylor screening function for exchange andcorrelation effects to the liquid d- and f-shellmetals. Here we clearly mention that the parameter of the potential isindependent of any fitting procedure either with any experimental dataor any theoretical values of any physical properties. The structurefactor derived by Percus-Yevick solution for hard sphere fluids, whichis characterized by hard sphere diameter, is used. A good agreementbetween theoretical investigations and experimental findings hasconfirmed the ability of the model potential to the liquid d-and f-shell metals.
