摘要：

The MAJORANA Collaboration is operating an array of high-purity Ge detectors to search for the neutrinoless double-beta decay of Ge-76. TheMAJORANA DEMONSTRATOR consists of 44.1 kg of Ge detectors (29.7 kg enriched to 88% in Ge-76) split between two modules constructed from ultraclean materials. Both modules are contained in a low-background shield at the Sanford Underground Research Facility in Lead, South Dakota. We present updated results on the search for neutrinoless double-beta decay in Ge-76 with 26.0 +/- 0.5 kg yr of enriched exposure. With the DEMONSTRATOR's energy resolution of 2.53 keV FWHM at Q(beta beta), which is the best among all neutrinoless double-beta decay experiments, we observe one event in the region of interest with 0.65 events expected from the estimated background, resulting in a lower limit on the Ge-76 neutrinoless double-beta decay half-life of 2.7 x 10(25) yr [90% confidence level (CL)] with a median sensitivity of 4.8 x 10(25) yr (90% CL). Depending on the matrix elements used, a 90% CL upper limit on the effective Majorana neutrino mass in the range of 200-433 meV is obtained. The measured background in the configurations with full shielding and optimized grounding is 11.9 +/- 2.0 counts/(FWHM t yr).
