Received 10 November 1994

The Brillouin-Wigner-Feenberg perturbation theory has been applied to a many-body fermion system, an electron gas at high density. The correlation energy has been calculated. An approximative expression of the term fr_s, is also derived. In our approximation, the calculated value of the constant f is equal to 0.8184.
