We report on the measurement of the two-neutrino double-beta decay half-life of Formula omittedTe with the CUORE-0 detector. From an exposure of 33.4 kg year of TeO Formula omitted, the half-life is determined to be Formula omitted = 8.2 ± 0.2 (stat.) ± 0.6 (syst.) Formula omitted 10 Formula omitted year. This result is obtained after a detailed reconstruction of the sources responsible for the CUORE-0 counting rate, with a specific study of those contributing to the Formula omittedTe neutrinoless double-beta decay region of interest.
