摘要：

Two measurements of the half-life of the 2-nu beta-beta-decay of Ge-76 are reported. One was made with the PNL-USC natural isotopic abundance germanium twin detectors. T1/2(2-nu) = (1.12 + (-0.26)+0.48)) x 10(21) y (2-sigma), and one with a Soviet-manufactured 0.25-kg Ge (Li) detector isotopically enriched to 85% in Ge-76, Ge, T1/2(2-nu) (9.2+ (-0.4)+0.7)) x 10(20) y (2-sigma). Both were measured in the same facility. These values are in good agreement with nuclear structure calculations and with an independent measurement by the ITEP-YPI collaboration.
