Abstract

The differential diffusion Monte Carlo method, involving correlated random walks, is used to calculate the static polarizabilities of molecular hydrogen and helium by application of a finite electrostatic field. The results are for molecular hydrogen (alpha)=4.60(3) au; (alpha)|=6.38(5) au; for helium (alpha) = 1.38(1) au. The results agree, within the statistical errors, with those obtained by application of high quality ab initio methods.
