Description
Double beta processes in 64Zn were searched for with the help of a low background ZnWO4 crystal scintillator (mass of 117 g) at the Gran Sasso National Laboratories of the INFN. Total time of measurements was 1902 h. New improved half-life limits on different modes of double electron capture and electron capture with positron emission were established as: T1/22ν2K≥6.2x1018 yr, T1/20ν2K≥4.0x1018 yr, T1/20ν2ε≥3.4x1018 yr, T1/22νεβ+≥2.1x1020 yr, and T1/20νεβ+≥2.2x1020 yr, all at 90% C.L
