Abstract
The CUPID-0 experiment searches for double beta decay using cryogenic calorimeters with double (heat and light) read-out. The detector, consisting of 24 ZnSe crystals 95\[\%\] enriched in \[^{82}\]Se and two natural ZnSe crystals, started data-taking in 2017 at Laboratori Nazionali del Gran Sasso. We present the search for the neutrino-less double beta decay of \[^{82}\]Se into the 0\[_1^+\], 2\[_1^+\] and 2\[_2^+\] excited states of \[^{82}\]Kr with an exposure of 5.74 kg\[\cdot \]yr (2.24\[\times \]10\[^{25}\] emitters\[\cdot \]yr). We found no evidence of the decays and set the most stringent limits on the widths of these processes: \[\varGamma \](\[^{82}\]Se \[\rightarrow ^{82}\]Kr\[_{0_1^+}\])8.55\[\times \]10\[^{-24}\] yr\[^{-1}\], \[\varGamma \] (\[^{82}\] Se \[\rightarrow ^{82}\] Kr \[_{2_1^+}\])\[\,{<}\,6.25 \,{\times }\,10^{-24}\] yr\[^{-1}\], \[\varGamma \](\[^{82}\]Se \[\rightarrow ^{82}\]Kr\[_{2_2^+}\])8.25\[\times \]10\[^{-24}\] yr\[^{-1}\] (90\[\%\] credible interval).
