Search for neutrinoless double beta decay with NEMO 3 experiment Original Research Article

NEMO 3 experiment is designed to search for neutrinoless double-beta decay (ββ0ν). 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 (ββ2ν) have been measured for seven isotopes. No evidence of neutrinoless beta decay has been found. The limits on both the half-lives of the ββ0ν and the corresponding Majorana effective masses are derived.
