Search for double- β decay processes in 108Cd and 114Cd with the help of the low-background CdWO 4 crystal scintillator.

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.
