Abstract
A magneto-optical trap and the new technique of full neutrino momentum reconstruction were used to account for massive neutrino admixtures in nuclear β 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.
