Diffusion Monte Carlo Method

The effects of interatomic potentials in the equation of state of 4 He and other properties of the system are investigated. A multi-weight diffusion Monte Carlo method is applied in order to compute very small energies differences with great accuracy. From our analysis we identify the best current description for the helium systems.
