Search for 2β decay of Zinc and Tungsten with the help of low-background ZnWO4 crystal scintillators


Double beta processes in 64Zn, 70Zn, 180W, and 186W have been searched for with the help of large volume (0.1 − 0.7 kg) low background ZnWO4 crystal scintillators at the Gran Sasso National Laboratories of the INFN. Total time of measurements exceeds 10 thousands hours. New improved half-life limits on double electron capture and electron capture with… (More)
