Abstract The results of the HEIDELBERG–MOSCOW experiment which searches with 11 kg of enriched 76 Ge for double beta decay in the Gran Sasso underground laboratory are presented for the full running period August 1990–May 2003. The duty cycle of the experiment was ∼80%, the collected statistics is 71.7 kg yr. The background achieved in the energy region of the Q value for double beta decay is 0.11 events kg −1 yr −1 keV −1 . The two-neutrino accompanied half-life is determined on the basis of more than 100 000 events. The confidence level for the neutrinoless signal has been improved to 4.2 σ .
