Abstract
The weighted-density approximation provides a direct link between the electron-electron pair distribution function and the response function of a homogeneous electron gas. Here we propose to use this relation as a closure for the fluctuation-dissipation equations to obtain in a closed form all the bulk properties of the system. The results are compared with previous theories and computer simulations.Keywords
