Abstract
In this work we present the results obtained measuring the 214Bi spectrum from a 226Ra source with a high purity germanium detector. Our attention was mostly focused on the energy region around the Q-value of 76Ge neutrinoless double-beta decay (2039.006 keV). The results of this measurement are strongly related to the first indication for the neutrinoless double beta decay of 76Ge, given by a recent analysis \cite{Evidence,KK02-PN,KK02-Found,KK-BigArt02} of the data collected during ten years of measurements from the HEIDELBERG-MOSCOW experiment.
