We present here an implementation of a combined variational and diffusion Monte Carlo (VMC and DMC) procedure that we have recently successfully used in describing the `solvation' of molecular and atomic ions in small He clusters. We report the details of our numerical procedure which may use both pure Metropolis sampling and Biased (Langevin) sampling. We conclude by showing a series of test calculations we have performed both on atomic and molecular impurities.

Abstract
We present here an implementation of a combined variational and diffusion Monte Carlo (VMC and DMC) procedure that we have recently successfully used in describing the `solvation' of molecular and atomic ions in small He clusters. We report the details of our numerical procedure which may use both pure Metropolis sampling and Biased (Langevin) sampling. We conclude by showing a series of test calculations we have performed both on atomic and molecular impurities.File in questo prodotto:
