| Abstract: | Alternative approaches to the calculation of two-neutrino double beta decay amplitudes are suggested which include neither the evaluation of the intermediate nucleus spectrum nor the closure approximation.Dedicated by the co-author to the memory of M. Gmitro.We wish to thank V. Belyaev, S. Bilenky, R. Eramzhyan, A. Ovchinnikova and E. Truhlik for interest and discussions. |
