Abstract: The Gerda experiment at the Laboratori Nazionali del Gran Sasso in Italy uses germanium detectors made from material with an enriched 76 Ge isotope fraction to search for neutrinoless double beta decay of this nucleus. Applying a blind analysis we find no signal after an exposure of 21.6 kg·yr and a background of about 0.01 cts/(keV·kg·yr). A half-life limit of T o v 1/2 > 2.1 · 10 25 yr (90% C.L.) is extracted. The previous claim of a signal for 76 Ge is excluded with 99% probability in a model independent way.
