NEMO 3 double beta decay experiment

The NEMO 3 detector is devoted to the search for neutrinoless double-beta decay (beta beta 0 nu). The expected performance of the detector has successfully achieved after the operation of a radon free air facility. Half-lives of double beta decay with two neutrinos (beta beta 2 nu) have been measured systematically for the 7 major nuclei ((100)Mo (82)Se, (116)Cd (150)Nd. (96)Zr, (48)Ca, (130)Te). There is no evidence of beta beta 0 nu, and the corresponding lower limits for the half-lives are (0)(1) (2)((100)Mo) 5.8 10 (23)y and (0)(1) (2)((82)Se) 2.1 10 (23)y at 90% C.L..
