摘要：

From the data taken with one of the enriched detectors of the Heidelberg-Moscow betabeta experiment a half-life of T1/2(2nu) = (1.42 +/- 0.03(stat)+/-0.13(syst)) X 10(21) yr for the two-neutrino double-beta (betabeta2nu) decay of Ge-76 is derived. The Ge-76 exposure is 19.3 mol yr. This result represents the first high statistics measurement and probably the first undoubtable evidence of this extremely rare nuclear decay mode. The measured decay rate is in good agreement with the theoretical predictions.
