Novel search for heavy mixing from the + decay of 38mK confined in an atom trap Academic Article uri icon


  • A magneto-optical trap and the new technique of full neutrino momentum reconstruction were used to account for massive neutrino admixtures in nuclear decay. It was possible to set the best direct limits on heavy vx admixtures into ve from mvx=0.7-3.6 MeV and the best model-independent direct limits from 2.9-3.6 MeV.
