Nuclear alignment and magnetic moments of Xe133, Xem133, and Xem131 by spin exchange with optically pumped Rb87

This paper reports the first demonstration of nuclear orientation of radioactive xenon atoms by spin exchange with polarized rubidium atoms. The nuclear tensor alignment, as measured by gamma-ray anisotropy, is about 30% of the maximum possible. The magnetic dipole moments for Xe133, Xem133, and Xem131 have also been measured by NMR spectroscopy. The methods developed here have possibilities for wide applications to nuclear and atomic studies of other radioactive rare-gas atoms.
