The Galitskii-Feynman-Hartree-Fock (GFHF) theory is outlined and applied to a system of fully polarized deuterium atoms. The effective interaction in this theory is the GFHF T-matrix. We give a calculation of the single particle energies, ɛ(\( \in (\vec k)\)), and the ground state energy as a function of density. The calculation of ɛ(\( \in (\vec k)\)) uses a new evaluation of the self energy which includes the effects of two hole intermediate states in the effective interaction. We also calculate the Landau parameters both from the T-matrix and from an induced interaction which uses the T-matrix as input. The good agreement of our ground state with the Monte Carlo calculations of Panoff and Clark and the internal consistency of our Landau parameters indicate that the T-matrix gives a good account of the effective interaction in this system.
