Abstract
The method of effective-potential expansion is successfully applied to a three-dimensional electron gas. Calculated correlation energies agree quite well with accurate Monte Carlo data. The difference is less than 1% for 1≤≤10. The static structure factor and pair-distribution function are also calculated. The latter is found to be always positive for these densities.
