Calculation of 2ν and 0ν Double-Beta Decay Rates

2ν and 0ν double-beta decay rates for all potential ββ emitters with A ≥ 70 are predicted. The nuclear transition matrix elements are calculated within the QRPA with a realistic effective nucleon-nucleon interaction. The results for neutrinoless decays are rather insensitive to details of the nuclear structure, except for the cases of 70Zn, 100Mo and 148Nd.
