    "abstract": "The effect of three-body interatomic contributions in the equation of state\nof 4He are investigated. A recent two-body potential together with the Cohen\nand Murrell (Chem. Phys. Lett. 260, 371 (1996)) three-body potential are\napplied to describe bulk helium. The triple-dipole dispersion and exchange\nenergies are evaluated subjected only to statistical uncertainties. An\nextension of the diffusion Monte Carlo method is applied in order to compute\nvery small energies differences. The results show how the three-body\ncontributions affects the ground-state energy, the equilibrium, melting and\nfreezing densities.",
