摘要
NEMO 3 experiment is designed to search for neutrinoless double-beta decay (beta beta 0 nu). It is located in the Modane Underground Laboratory (LSM) and has been taking data since February 2003. The half-lives of two-neutrino double-beta decay (beta beta 2 nu) have been measured for seven isotopes. No evidence of neutrinoless beta decay has been found. The limits on both the half-lives of the beta beta 0 nu and the corresponding Majorana effective masses are derived.
