Abstract
The ground-state magnetic dipole and electric quadrupole moments of the emitter (, s) have been measured for the first time. Polarized nuclei were produced in the reaction, using 5-6 MeV polarized tritons. The recoiling nuclei were stopped either in Au foils or in LiNb single crystals, and their polarization was detected by measuring the -decay asymmetry. Nuclear magnetic resonance techniques were used to depolarize the nuclei, and the resonant frequencies were deduced from changes in the asymmetry. The dipole moment was deduced from the measured Larmor frequency in Au; the result, including corrections for diamagnetic shielding and the Knight shift, is . The ratio of the quadrupole moment to that of was derived from their respective quadrupole couplings in LiNb; the value is . Both results are in agreement with shell model predictions.
