Summary: | 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:
