Search for the double-beta decay of 82Se to the excited states of 82Kr with NEMO-3
Original language description
The double-beta decay of 82Se to the 01 + excited state of 82Kr has been studied with the NEMO-3 detector using 0.93 kg of enriched 82Se measured for 4.75 y, corresponding to an exposure of 4.42 kg⋅y. A dedicated analysis to reconstruct the γ-rays has been performed to search for events in the 2e2γ channel. No evidence of a 2νββ decay to the 01 + state has been observed and a limit of T1/2 2ν(Se82,0gs +->01 +)>1.3x1021y at 90% CL has been set. Concerning the 0νββ decay to the 01 + state, a limit for this decay has been obtained with T1/2 0ν(Se82,0gs +->01 +)>2.3x1022y at 90% CL, independently from the 2νββ decay process. These results are obtained for the first time with a tracko-calo detector, reconstructing every particle in the final state.
