Final Results of GERDA on the Two-Neutrino Double-$\beta$ Decay Half-Life of ${}^{76}$Ge

GERDA collaboration, M. Agostini, A. Alexander +116

We present the measurement of the two-neutrino double-$\beta$ decay rate of ${}^{76}$Ge performed with the GERDA Phase II experiment. With a subset of the entire GERDA exposure, 11.8 kg$…
