摘要：

The International Germanium Experiment (IGEX) has six detectors, containing >90 fiducial moles of Ge-76, operating underground. Data thus far yield T-1/2(2v) = (1.1 +/- 0.2) x 10(21)y and T-1/2(0v) > 4.2 x 10(24)y(90% CL) if interpreted as a null experiment, or T-1/2(0v) > 3.3 x 10(24)y(95% CL) in a more conservative case.
