Observation of Two-Neutrino Double-Beta Decay in [superscript 136]Xe with the EXO-200 Detector
We report the observation of two-neutrino double-beta decay in [superscript 136]Xe with T[subscript 1/2]=2.11±0.04(stat)±0.21(syst)×10[superscript 21] yr. This second-order process, predicted by the standard model, has been observed for several nuclei but not for [superscript 136]Xe. The observed d...
