Monte Carlo simulations of soft spheres interacting through inverse power potentials, u(r)??r-n, have been performed. Poisson's ratio of the soft sphere face-centred cubic crystals were determined using the constant pressure ensemble with variable box shape. It was shown that at high densities, particle motions decrease Poisson's ratio with respect to the static case which corresponds to zero temperature. It was also shown that increasing the exponent n in the potential, one can decrease Poisson's ratio.
