The nuclear electric quadrupole moments of the isotopes Na, Na, Na and Na were measured by -NMR spectroscopy in single crystals of LiNbO and NaNO. High degrees of nuclear polarization were produced by optical pumping of the sodium atoms in a fast beam with a collinear laser beam. The polarized nuclei were implanted into the crystals and NMR signals were observed in the -decay asymmetries. Preparatory measurements also yielded improved values for the magnetic moments of Na and confirmed the spin = 3/2 for Na. The results are discussed in comparison with large-basis shell model calculations.
