Theoretical matrix elements, for the ground-state to ground-state two-neutrino double-beta-decay mode of {sup 128,130}Te isotopes, are calculated within a formalism which describes interactions between neutrons in a superfluid phase and protons in a normal phase. The model is basically a parameter-free one, since all relevant parameters are fixed from phenomenology. A comparison with the available experimental data is presented.
