Abstract
A self-consistent many-body procedure capable of handling the problem of correlation among Bloch electrons in metals is developed. Application to the uniform electron gas for several densities, in the range , leads to correlation energies and compressibilities in good agreement with results from recent sophisticated dielectric treatments. The space pair-correlation function for parallel spins obtained by this treatment is positive over the entire range of .
