Using 9.4 g of 96Zr and 1221 days of data from the NEMO-3 detector corresponding to 0.031 kg
y, the obtained 2 decay half-life measurement is T 2 1=2 = [2:35  0:14(stat)  0:16(syst)]  1019 yr. Dierent characteristics of the final state electrons have been studied, such as the energy sum, individual electron energy, and angular distribution. The 2 nuclear matrix element is extracted using the measured 2 half-life and is M2 = 0:049  0:002. A 90% CL limit is set on the 0 decay half-life of T0 1=2 > 9:2  1021 yr corresponding to a limit on the eective Majorana neutrino mass of hmi < 7:2 �� 19:5 eV. Limits on other mechanisms of 0 decay have also been set.
