EXO-200 precisely measures ultra-rare decay

Publication date: Thu, Jan 30, 2014 - 11:03am

The EXO-200 experiment has measured the 2-neutrino double-beta decay of Xe-136 with 3% precision. The measurement provides useful information for modeling the Xe-136 nucleus, and places Xe-136 on the front stage in the search for the lepton number-violating neutrino-less double beta decay. The EXO-200 collaboration includes professors Andrea Pocar and Krishna Kumar, postdoc Tim Daniels, and graduate student Sereres Johnston. The result is highlighted on Physical Review C. ( ...more… )
