摘要：

The nuclear quadrupole moments of neutron-rich sodium isotopes are being investigated with the help of in-beam polarization by optical pumping in combination with beta-NMR techniques. First measurements have yielded the quadrupole splittings of NMR signals in the lattice of LiNbO3 for the isotopes Na-26, Na-27 and Na-28. Interaction constants and ratios of the electric quadrupole moments are derived. In view of future experiments, beta-decay asymmetries for the sequence of isotopes up to the N = 20 neutron shell closure, Na-26-31, have been measured.
