Trapping of polarized ²1Na — •Wilbert Kruithof, Duurt Johan van der Hoek, Moslem Sohani, Lorenz Willmann, Hans Wilschut, and Klaus Jungmann — KVI, University of Groningen

²1Na is an excellent candiate to look for symmetry violations in nuclear β-decay. It is produced at sufficient quantities at the TRIµP facility of KVI. The atoms are stored in a maneto-optical trap. The decay products – an energetic positron and a recoiling Ne ion –, are detected in an energy and position sensitive scintillation particle detector and a reaction microscope, respectively. The sensitivity to symmetry violating amplitudes lies in the correlations between kinematic variables of these reaction products. Additional scalar and tensor components in the interaction can be found , e.g., in the decays of unpolarized Na atoms. Time reversal violation can be probed using polarized samples. The trapping of radioactive Na will be discussed and the sensitivity limits of such an experiment will be reported.
