    "abstract": "The lifetimes for the double beta decays of $^{76}$Ge, $^{82}$Se and\n$^{136}$Xe are calculated using very large shell model spaces. The two neutrino\nmatrix elements obtained are in good agreement with the present experimental\ndata. For $\u003cm_{\\nu}\u003e\u003c1$ eV we predict the following upper bounds to the\nhalf-lives for the neutrinoless mode: $T^{(0\\nu)}_{1/2}(Ge) \u003e 1.85\\,10^{25}\nyr.$, $T^{(0\\nu)}_{1/2}(Se) \u003e 2.36\\,10^{24} yr.$ and $T^{(0\\nu)}_{1/2}(Xe) \u003e\n1.21\\,10^{25} yr$. These results are the first from a new generation of Shell\nModel calculations reaching O(10$^{8}$) dimensions.",
