Production of Nuclear Polarization of Na Isotopes at ISAC/TRIUMF and its Hyperfine Interaction.

Hyperfine interactions of Na isotopes in single crystals have been studied using highly nuclear polarized ^{20,21,26,27,28}Na beams provided by ISAC/TRIUMF. The degree of polarization kept in the crystals, the spin-lattice relaxation times, the electric quadrupole coupling constants and the initial distribution of the populations were measured. Such knowledge is indispensable for the application of the hyperfine interactions in the study of precision measurements such as the nuclear structure through nuclear moments and the fundamental symmetries.
