An isolated cluster method has been implemented to avoid the finite size error in Quantum Monte Carlo (QMC). With this method, the dissociation energy of solid can be obtained by extrapolating several finite size clusters into infinite. As an example, the dissociation energy of MgH 2 is predicted, a
