We report on a search for double beta decay of 130 Te to the first 0 + excited state of 130 Xe using a 9.8 kg · yr exposure of 130 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 1 + 0 ν > 7.9 · 10 23 yr and T 0 1 + 2 ν > 2.4 · 10 23 yr ( 90 % CL ). Combining our results with those obtained by the CUORICINO experiment, we achieve the most stringent constraints available for these processes: T 0 1 + 0 ν > 1.4 · 10 24 yr and T 0 1 + 2 ν > 2.5 · 10 23 yr ( 90 % CL ).
