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