摘要：

NEMO 3 is a currently running experiment to search for the neutrinoless double beta decay (0 nu beta beta) and to study the two-neutrino double beta decay (2 nu beta beta) with 10kg of enriched isotopes. No evidence for the 0 nu beta beta-decay is found after 1409 effective days of data collection with 7 kg of Mo-100, T-1/2(0 nu) > 1.1 . 10(24) yr at 90% CL, and with 1 kg of Se-82,T-1/2(0 nu) > 3.6 . 10(23) yr at 90% CL. The corresponding limits on the effective Majorana neutrino mass are < m(v)> < 0.45 - 0.93 eV for Mo-100 and (m,) < 0.89 - 2.43 eV for Se-82 depending on the nuclear matrix element calculations.
