Description
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 01+, 21+ and 22+ excited states of 82 Kr with an exposure of 5.74 kg· yr (2.24× 10 25 emitters· yr). We found no evidence of the decays and set the most stringent limits on the widths of these processes: Γ( 82 Se → 82 Kr01+)8.55× 10 - 24 yr - 1 , Γ ( 82 Se → 82 Kr 21+)<6.25×10-24 yr - 1 , Γ( 82 Se → 82 Kr22+)8.25× 10 - 24 yr - 1 (90% credible interval).
