Abstract

The primary goal of the GERmanium Detector Array (GERDA) experiment at the Laboratori Nazionali del Gran Sasso of INFN is the search for the neutrinoless double beta decay of ⁷⁶Ge. High-purity germanium detectors made from material enriched in ⁷⁶Ge are operated directly immersed in liquid argon, allowing for a substantial reduction of the background with respect to predecessor experiments. The first 5.04 kg yr of data collected in Phase I of the experiment have been analyzed to measure the half-life of the neutrino-accompanied double beta decay of ⁷⁶Ge. The observed spectrum in the energy range between 600 and 1800 keV is dominated by the double beta decay of ⁷⁶Ge. The half-life extracted from GERDA data is T ^2ν1/2 = (1.84^+0.14-0.10) × 10²¹ yr.
