Background coming from the $$^{42}$$42Ar decay chain is considered to be one of the most relevant for the Gerda experiment, which searches for the neutrinoless double beta decay of $$^{76}$$76Ge. The sensitivity strongly relies on the absence of background around the Q-value of the decay. Background coming from $$^{42}$$42K, a progeny of $$^{42}$$42Ar, can contribute to that background via electrons from the continuous spectrum with an endpoint at 3.5 MeV. Research and development on the…
