    "abstract": "Shell Model Monte Carlo (SMMC) techniques are used to calculate two-neutrino\ndouble beta decay matrix elements. We validate the approach against direct\ndiagonalization for $^{48}$Ca in the complete $pf$-shell using the KB3\ninteraction. The method is then applied to the decay of $^{76}$Ge in the\n$(0f_{5/2},1p,0g_{9/2})$ model space using a newly calculated realistic\ninteraction. Our result for the matrix element is $0.13\\pm0.05$ MeV$^{-1}$, in\nagreement with the experimental value.",
