Rare alpha decays of natural Hf isotopes
A small series of four caesium hafnium chloride (Cs 2 HfCl 6 , CHC) crystal scintillators has been measured in a low-background setup at the Gran Sasso National Laboratory of the INFN, Italy. After characterization of the detectors, new measurements concerning the rare alpha activity of natural Hf isotopes have been done. Based on cumulative data collected over 85.23 d, a new half-life value for the 174 Hf α decay has been obtained: ( 2.95 − 0.14 + 0.15 ( stat ) ± 0.09 ( sys ) ) × 10 16 year. This result is consistent with that reported earlier, which was obtained using one of the CHC crystals employed in the present work, albeit within a different experimental setup. The combined value is T 1 / 2 = (2.95 ± 0.16) × 10 16 year. These measurements have resolved the long-standing discrepancy between the previously available experimental values and theoretical predictions. The experimental limits on the half-lives for α decay of other natural Hf isotopes have been derived in the range of 10 19 − 10 20 year (90% C.L.). The limit for the α decay of 180 Hf was set for the first time.

Search for sterile neutrinos with CUPID-0
Sterile neutrinos are well-motivated extensions of the Standard Model, introduced to address fundamental questions such as the origin of neutrino masses and the nature of dark matter. Exploiting the precise data reconstruction achieved by the CUPID-0 experiment, we searched for spectral distortions in the double β-decay of 82Se compatible with the emission of a sterile neutrino. The analysis relies on the construction of a detailed background model down to 200 keV, enabling an accurate characterization of the main sources of contamination. Using a Zn82Se exposure of 9.95 kg·yr, we explored sterile neutrino mass hypotheses between 0.5 MeV and 1.5 MeV. No evidence for a signal was observed in any scenario; therefore, we derived 90% C.I. upper limits on the active-sterile mixing probability sin2 θ, obtaining the most stringent bound, sin2 θ < 8 × 10-3, for a sterile neutrino mass of 0.7 MeV.

Performances of a SrI$_2$(Eu) crystal scintillator and its application to the search of $^{84}$Sr $\beta \beta $ decayA new strontium iodide crystal doped by europium (SrI $$_2$$ (Eu); mass $$\,\simeq \,$$ 130 g) was produced by selected materials using the vertical Bridgman method. It was measured over 4140 h deep underground at the Gran Sasso National Laboratory (LNGS) of the INFN in the DAMA/CRYS low-background set-up. A characterization of the crystal features and performances has preliminarily been investigated. The obtained results have been used in the search for the double electron capture and electron capture with positron emission in $$^{84}$$ Sr; new and improved limits have been achieved for these processes, with half-lives $$T_{1/2}$$ reaching the level of several 10 $$^{17}$$ yr. Further improvements of low background techniques in the SrI $$_2$$ (Eu) crystal development would offer additional increase of reachable experimental sensitivities on $$^{84}$$ Sr $$\beta \beta $$ decay modes.- 2 June 2026

Search for double-electron capture in 152 Gd with GAGG:Ce scintillator
Double-electron capture in 152 Gd was searched for over 1336 h with a 286-g GAGG:Ce crystal scintillator at the Gran Sasso underground laboratory of the INFN (Italy). New, improved by four orders of magnitude, limit on the near-resonant 0ν2EC capture in 152 Gd was set as lim T 1/2 = 8.1 x 10 16 yr at 90% C.L. Moreover, for the first time, a laboratory experiment has established a lower limit on the half-life of the allowed 2νKL process in the nuclide, with lim T 1/2 = 9.2 x 10 16 yr at 90% C.L.

New Results of the Experiment to Search for Double Beta Decay of 106Cd with Enriched 106CdWO4 Scintillator
In this article, we present current results of the experiment searching for double beta decay of 106Cd with the help of an enriched 106CdWO4 crystal scintillator in coincidence with two CdWO4 scintillation detectors. The experiment is carried out at the Gran Sasso underground laboratory of the National Institute for Nuclear Physics (LNGS INFN, Italy). After 1075 days of data-taking, no double-beta effects were observed. New half-life limits have been set for the different modes and channels of double beta processes in 106Cd at the level of years.Open AccessNew Results of the Experiment to Search for Double Beta Decay of 106Cd with Enriched 106CdWO4 Scintillator

Double-beta decay of $^{150}\hbox {Nd}$ to excited levels of $^{150}\hbox {Sm}$The $$2\nu 2\beta $$ decay of $$^{150}\hbox {Nd}$$ to the first excited 740.5 keV $$0^{+}_{1}$$ level of $$^{150}\hbox {Sm}$$ was measured over 5.845 years with the help of a four-crystal low-background HPGe $$\gamma $$ spectrometry system in the underground low-background laboratory STELLA of LNGS-INFN. A 2.381 kg highly purified Nd-containing sample was employed as the decay source. The expected de-excitation gamma-quanta of the $$0^{+}_{1}$$ level with energies 334.0 keV and 406.5 keV were observed both in one-dimensional spectrum and in coincidence data resulting in the half-life $$T_{1/2}=[0.83^{+0.18}_{-0.13}\mathrm {(stat)}^{+0.16}_{-0.19}\mathrm {(syst)}]\times 10^{20}$$ year. Interpreting an excess of the 334.0-keV peak area as an indication of the $$2\beta $$ decay of $$^{150}\hbox {Nd}$$ to the 334.0 keV $$2^+_1$$ excited level of $$^{150}\hbox {Sm}$$ with a half-life of $$T_{1/2}=[1.5^{+2.3}_{-0.6}\mathrm {(stat)}\pm 0.4\mathrm {(syst)}]\times 10^{20}$$ year, the $$2\nu 2\beta $$ half-life of $$^{150}\hbox {Nd}$$ for the transition to the 0 $$^{+}_{1}$$ level is $$T_{1/2}=[1.03^{+0.35}_{-0.22}\mathrm {(stat)}^{+0.16}_{-0.19}\mathrm {(syst)}]\times 10^{20}$$ year, in agreement with the previous experiments. Both half-life values reasonably agree with the theoretical calculations in the framework of proton-neutron QRPA with isospin restoration combined with like nucleon QRPA for description of excited states in the final nuclei. For $$2\nu 2\beta $$ and $$0\nu 2\beta $$ transitions of $$^{150}\hbox {Nd}$$ and $$^{148}\hbox {Nd}$$ to several excited levels of $$^{150}\hbox {Sm}$$ and $$^{148}\hbox {Sm}$$ , limits were set at level of $$T_{1/2}>10^{20}-10^{21}$$ year.- 11 February 2025
