Abstract
Starting from Mori's formalism, an expression for the dynamical structure factor for the electron liquid is derived. The memory function is calculated such that no phenomenological collision rates have to be introduced. Using simple approximations for some static correlation functions, good agreement with inelastic x-ray experiments is obtained.Keywords
