Abstract
We suitably modify the scheme of Singwi et al. for calculating the density response function of interacting electron gas to take into account the fact that the pair correlation function vanishes in the highly repulsive hard-core region of the potential for classical liquids. This modified self-consistent iterative scheme is applied to calculate the structure factor for liquid sodium and rubidium. Both equilibrium and dynamical properties of classical liquids can now be calculated from a single theory.
