چکیده
Recent observation of β decay of 115 In to the first excited level of 115 Sn with an extremely low Q β value (Q β ≤ O(1) keV) could be used to set a limit on neu-trino mass. To give restriction potentially competitive with those extracted from experiments with 3 H (≃2 eV) and 187 Re (≃15 eV), atomic mass difference between 115 In and 115 Sn and energy of the first 115 Sn level should be remeasured with higher accuracy (possibly of the order of ∼1 eV).

In the context of the LENS R&D solar neutrino project, the γ spectrum of a sample of metallic indium was measured using a single experimental setup of 4 HP-Ge detectors located underground at the Gran Sasso National Laboratories (LNGS), Italy. A γ line at the energy (497.48±0.21) keV was found that is not present in the background spectrum and that can be identified as a γ quantum following the...

The double beta decay of 100Mo to the 01 and 2 + 1 excited states of 100Ru is studied using the NEMO 3 data. After the analysis of 8024 h of data the half-life for the two-neutrino double beta decay of 100Mo to the excited 01 state is measured to be T (2ν) 1/2 = [5.7 +1.3 −0.9(stat)±0.8(syst)]·10 y. The signal-to-background ratio is equal to 3. Information about energy and angular distributions...

The Aurora experiment to investigate double beta decay of Cd with the help of 1.162 kg cadmium tungstate crystal scintillators enriched in Cd to 82% is in progress at the Gran Sasso Underground Laboratory. The half-life of Cd relatively to the two neutrino double beta decay is measured with the highest up-to-date accuracy T1/2 = (2.62 ± 0.14) × 10 yr. The sensitivity of the experiment to the ne...
