摘要
The background in the region of the Q-value for neutrinoless double beta decay of Ge-76 has been investigated by different methods: Simulation with GEANT 4 of the HEIDELBERG-MOSCOW experiment and analysis of other Ge double beta experiments. Statistical features of the analysis at very low count rates are discussed. (C) 2003 Elsevier B.V. All rights reserved.
