摘要：

We estimate the double-beta half-life in the two-neutrino mode of several heavy deformed nuclei using the pseudo SU(3) shell-model scheme. In this approach, we used a recently developed summation procedure, avoiding the closure approximation. We find forbidden decays for five potential double-beta emitters and finite values for the half-life of six other nuclei, one of them strongly inhibited. These forbidden decays represent a possible test of our model and up to now the predictions are in good agreement with the available experimental data.
