| Abstract: | New results are presented from an experiment on double beta decay of 76Ge carried out with two Ge Li detectors in the Mont Blanc tunnel. No evidence has been found for neutrinoless double beta decay, and the obtained lower limit of the half lifetime (1.2 × 1023 yr) is discussed in terms of the mass of Majorana neutrinos and of the possible presence of right-handed currents. |
