Observation of 2β 2ν decay of 150Nd in an experiment with the time projection chamber
The time projection chamber has been used in a magnetic field to determine the decay half-life of 150Nd. Measurements on a sample of the isotope 150Nd (92% enrichment) and a sample with the natural isotopic composition, natNd, reveal Τι/2(2β2ν) = (1.7±J;°±0.35) Χ 1019 yr. The effect-to-background ratio is 4/1.
