Abstract

The authors recently evaluated the local field factor, G(q) of the electron gas by accurate fixed-node diffusion Monte Carlo (DMC) simulations. Here, the G(q) obtained from a simple fit to the DMC results and from several approximations available in the literature is used to derive the effective pair potential phi(r) in simple metals within second-order perturbation theory. Using a local electron-ion pseudopotential, it is found that phi is determined mostly by the behavior of G(q) atq less than or equal to ca. 2q(F), where the DMC data are well reproduced by the local field within local density approximation, G(LDA)) = A(q/q(F))(2) with A related to the compressibility of the uniform electron gas.
