Search for double beta decay of 82Se with the NEMO-3 detector and development of apparatus for low-level radon measurements for the SuperNEMO experiment
The 2νββ half-life of 82Se has been measured as (9.93 ± 0.14 (stat) ± 0.72 (syst)) × 10^19 yr using a 932 g sample measured for a total of 5.25 years in the NEMO-3 detector. The corresponding nuclear matrix element is found to be 0.0484 ± 0.0018. In addition, a search for 0νββ in the same isotope ha...
