A tin-loaded liquid scintillator approach for the 2 neutrino double-beta decay measurement of Sn-124
Abstract
A new experiment based on tin-loaded scintillator is proposed to measure the 2nu double beta decay half-life of Sn-124 for the first time. Measurements of long term stabilitiy and optical properties of the produced scintillator are presented. In addition a sophisticated estimation of the background due to cosmic ray spallation on tin has been performed. It is shown that such a measurement is feasible and can reach half-lives of 1022 years, thus covering all current theoretical predictions for this decay mode.
