Abstract
The discrepancies that exist between theory and experiment in the ground-state energy and the liquid structure function of He4 are not insignificant. We show via a two-dimensional Monte Carlo calculation that by incorporating explicit three-particle correlation factors into the variational wave function, both the energy and the liquid structure function are improved in the right direction. This suggests that the discrepancies need not be attributed to the choice of the potential.
