A discussion of the idealized problem of the ground state energy of a gas of electrons in the presence of a uniform background of positive charge that makes the system neutral. The quantity <> is defined as the correlation energy per particle of an electron gas expressed in Rydbergs. It is a function of the conventional dimensionless parameter r[subscript s], where r[subscript s]** is proportional to the electron density. The method of computation is based on summing the most highly divergent terms of the perturbation series under the integral sign to give a convergent result.
