• 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 [Formula omitted] enriched in [Formula omitted]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 [Formula omitted]Se into the 0 [Formula omitted], 2 [Formula omitted] and 2 [Formula omitted] excited states of [Formula omitted]Kr with an exposure of 5.74 kg [Formula omitted]yr (2.24 [Formula omitted]10 [Formula omitted] emitters [Formula omitted]yr). We found no evidence of the decays and set the most stringent limits on the widths of these processes: [Formula omitted]( [Formula omitted]Se [Formula omitted]Kr [Formula omitted])8.55 [Formula omitted]10 [Formula omitted] yr [Formula omitted], [Formula omitted] ( [Formula omitted] Se [Formula omitted] Kr [Formula omitted]) [Formula omitted] yr [Formula omitted], [Formula omitted]( [Formula omitted]Se [Formula omitted]Kr [Formula omitted])8.25 [Formula omitted]10 [Formula omitted] yr [Formula omitted] (90 [Formula omitted] credible interval).
