TL;DR: Arnold et al. as mentioned in this paper measured the double beta decay of Nd to the 0 + 1 and 2 + 1 excited states of Sm in NEMO-3 with data recorded during 5.25 y with 36.6 g of the isotope Nd.
Abstract: NEMO-3 results for the double beta decay of Nd to the 0 +1 and 2 + 1 excited states of Sm are reported. The data recorded during 5.25 y with 36.6 g of the isotope Nd were used in the analysis. For the first time the signal of 2νββ transition to the 0+1 excited state is detected with statistical significance exceeding 5 sigma. The half-life is measured to be T 2νββ 1/2 (0 + 1 ) = [ 1.11 −0.14 (stat) +0.17 −0.15 (syst) ] × 10 y. Limits are set on 2νββ decay to 2+1 level and on 0νββ decay to 0 + 1 and 2 + 1 levels of Sm. ar X iv :2 20 3. 03 35 6v 1 [ nu cl -e x] 7 M ar 2 02 2 2 R.

TL;DR: In this paper , the neutrino-less double beta decay (0$ u\beta\beta$) of $^{48}$Ca with the CANDLES III system, which consists of CaF$2}$(pure) scintillators.
Abstract: We have studied the neutrino-less double beta decay(0$ u\beta\beta$) of $^{48}$Ca with the CANDLES III system, which consists of CaF$_{2}$(pure) scintillators. The first result of $^{48}$Ca double beta decay with the CANDLES III system was obtained by using 130.4 days of data. In this measurement, we achieved a background free measurement and a low background condition of 10$^{-3}$ events/keV/yr/(kg of $^{\rm nat.}$Ca). The sensitivity of this measurement, however, was limited by the small amount of $^{48}$Ca. For a more sensitive measurement of $^{48}$Ca 0$ u\beta\beta$, we have developed new techniques for $^{48}$Ca enrichment and CaF$_{2}$ scintillating bolometer. In this paper, we will also show the current status of these techniques.
