Exotic nuclear decay noticed in unlit-matter detector – physicsworld.com

Rare event: the XENON1T time projection chamber after assembly. (Courtesy: XENON Collaboration) An exotic and extremely rare nuclear decay that involves the simultaneous capture of two atomic electrons by a xenon-124 nucleus has been observed in a dark-matter detector.
