摘要：

Two-neutrino double beta decay of Mo-100 with half-life T-1/2 = [7.2 +/- 0.9(stat) +/- 1.8(syst)] x 10(18) yr was detected using a liquid argon ionization chamber. With a C.L. of 68% (90%), the bounds on neutrinoless decay and decay with majoron emission were found to be 8.4(4.9) x 10(21) and 4.1(3.2) x 10(20) yr, respectively. An analysis of all available results provides the average "world" value T-1/2 = (8.0 +/- 0.7) x 10(18) yr for the two-neutrino decay of Mo-100, and the corresponding nuclear matrix element is M-GT = 0.118 +/- 0.005.
