Using data from the NEMO-3 experiment, we have measured the two-neutrino double beta decay ( $2\nu \beta \beta $ ) half-life of$^{82}$ Se as $T_{\smash {1/2}}^{2\nu } \!=\! \left[ 9.39 \pm 0.17\left( \text{ stat }\right) \pm 0.58\left( \text{ syst }\right) \right] \times 10^{19}$ y under the single-state dominance hypothesis for this nuclear transition. The corresponding nuclear matrix element is $\left| M^{2\nu }\right| = 0.0498 \pm 0.0016$ . In addition, a search for neutrinoless double beta decay ( $0\nu \beta \beta $ ) using 0.93 kg of$^{82}$ Se observed for a total of 5.25 y has been conducted and no evidence for a signal has been found. The resulting half-life limit of $T_{1/2}^{0\nu } > 2.5 \times 10^{23} \,\text{ y } \,(90\%\,\text...
