Phys. Rev. A 35, 3901–3910 (1987)van der Waals perturbation theory for fermion and boson ground-state matterReceived 3 December 1986; published in the issue dated May 1987 Using computer algebraic symbolic manipulation techniques, we rearrange the ideal-gas-based low-density expansions for the ground-state energy of a many-fermion and a many-boson system interacting via arbitrary pair central forces, into a repulsive-core-fluid-based perturbation expansion. Applications through second order are reported for liquid 4He and liquid 3He. © 1987 The American Physical Society URL:
