$\beta$-NMR measurement of the nuclear quadrupole moments of $^{20,26-31}$Na

The quadrupole moments of the neutron-rich isotopes $^{26-31}$Na and of the neutron-deficient $^{20}$Na were measured by $\beta$-NMR after implantation of the short-lived nuclei into the host crystal lattices of Mg, LiNbO$_{3}$ and NaNO$_{3}$. The ion beams from ISOLDE were neutralized and polarized...

Sumario:The quadrupole moments of the neutron-rich isotopes $^{26-31}$Na and of the neutron-deficient $^{20}$Na were measured by $\beta$-NMR after implantation of the short-lived nuclei into the host crystal lattices of Mg, LiNbO$_{3}$ and NaNO$_{3}$. The ion beams from ISOLDE were neutralized and polarized by in-beam optical pumping. Of particular interest are the isotopes close to N=20 for which various experimental observations suggest rather strong deformation. (5 refs) .
