“…Other materials or locations in the detector array are negligible due their small masses and low activities. The following background components were simulated: the natural decay chains of 238 U and 232 Th, 40 K, cosmogenic and anthropogenic isotopes, muon showers and neutron induced interactions. It was assumed that the 238 U and 232 Th decay chains are in secular equilibrium and that the radioactive isotopes in the respective materials are uniformly distributed.…”

“…The measured neutron flux in the Gran Sasso underground laboratory [19] was simulated using the MICAP implementation in Geant [20]. The activities of 40 K and 210 Pb in the LC2-Pb shield were determined in separate activity measurements [21]. In order to extract the best fit values for each activity, a least-squares method has been used.…”

Abstract. New results for the double beta decay of76 Ge are presented. They are extracted from Data obtained with the Heidelberg-Moscow experiment, which operates five enriched 76 Ge detectors in an extreme low-level environment in the Gran Sasso underground laboratory. The two neutrino accompanied double beta decay is evaluated for the first time for all five detectors with a statistical significance of 47.7 kg y resulting in a half life of T
