Abstract.

The search for double-β processes in 108Cd and 114Cd was realized by using data of the low-background experiment with the CdWO4 crystal scintillator at the Gran Sasso National Laboratories of the INFN. New improved half-life limits on double-beta processes were established, in particular T 1/2 0ν2ɛ( ^108Cd ) ≥ 1.0(2.7)×1018 yr, T 1/2 2ν2β( ^114Cd ) ≥ 1.3(2.1)×1018 yr, and T 1/2 0ν2β( ^114Cd ) ≥ 1.1(2.5)×1021 yr at 90(68)% C.L.
