DOIAbstract
International audienceWe report on a search for double beta decay of$^{130}\hbox {Te}$ to the first $0^{+}$ excited state of$^{130}\hbox {Xe}$ using a $9.8\,\hbox {kg}\cdot \hbox {yr}$ exposure of$^{130}\hbox {Te}$ collected with the CUORE-0 experiment. In this work we exploit different topologies of coincident events to search for both the neutrinoless and two-neutrino double beta decay modes. We find no evidence for either mode and place lower bounds on the half-lives: $T^{0\nu 0^+_1}>7.9\cdot 10^{23}\hbox {yr}$ and $T^{2\nu 0^+_1}>2.4\cdot 10^{23}\hbox {yr}$ ( $90\%\,\hbox {CL}$ ). Combining our results with those obtained by the CUORICINO experiment, we achieve the most stringent constraints available for these processes: $T^{0\nu 0^+_1...
