Abstract
Shell Model Monte Carlo (SMMC) techniques are used to calculate two-neutrino double beta decay matrix elements. We validate the approach against direct diagonalization for Ca in the complete -shell using the KB3 interaction. The method is then applied to the decay of Ge in the model space using a newly calculated realistic interaction. Our result for the matrix element is MeV, in agreement with the experimental value.
