Abstract: Using 1221 days of data from the NEMO--3 detector, the measurement of Zr-96 2vbb decay half-life is [2.35 +- 0.14(stat) +- 0.19(syst)]x10^19 yr. A 90% CL limit is set on the 0vbb decay half-life of > 9.2 x10^21 yr corresponding to a limit on the effective Majorana neutrino mass of < 7.2-19.5 eV.
