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