چکیده انگلیسی
By solving the thermodynamic equation of pressure and using the pseudopotential approach, the effective inter-ionic potential function for alkali metals near their melting points is obtained. To obtain an exact equilibrium interatomic distance, a modified form of the inter-ionic potential function involved in the pseudopotential formulation is presented. The modified potential function is applied to derive the thermodynamic equation of pressure, and then the inter-ionic potential parameters are obtained by fitting the experimental PVT data. Obtained from macroscopic properties, the form of the characterized potential function is in good agreement with the potential from structure factor.
