  The International Germanium Experiment (IGEX) has analyzed 117 mole yr of
76Ge data from its isotopically enriched (86% 76Ge) germanium detectors.
Applying pulse-shape discrimination (PSD) to the more recent data, the lower
bound on the half-life for neutrinoless double-beta decay of 76Ge is:
$T_{1/2}(0\nu)> 1.57 \times 10^{25}$ yr (90% C.L.). This corresponds to an
upper bound in the Majorana neutrino mass parameter,$<m_{\nu}>$, between 0.33
eV and 1.35 eV, depending on the choice of theoretical nuclear matrix elements
used in the analysis.
