Scott Haselschwardt – an Owen Chamberlain Postdoctoral Fellow in Berkeley Lab’s Physics Division – and collaborators from SLAC National Accelerator Laboratory, the University of North Carolina – Wilmington, and Duke University, have recently reported on their determination of new nuclear data for cesium-136, specifically the properties of its low-lying excited states. These data will allow researchers to reliably model the emission of gamma rays following so-called “charged-current” neutrino-nucleus interactions in large xenon detectors, such as the LUX-ZEPLIN experiment. The study of such reactions will enable new measurements of solar neutrinos and more powerful searches for certain models of dark matter.
