| Abstract | A β-detected nuclear quadrupole resonance (NQR) spectrometer becomes a powerful tool to study changes in nuclear ground-state properties along isotopic chains when coupled to a laser excitation beamline to polarize the nuclei of interest. Recently, the β-NQR technique in a zero magnetic field has been applied for the first time to measure the ratio of static nuclear quadrupole moments of 8, 9 Li, Q 9 / Q 8 = 0.966 75(9) denoted by Q 8 for 8 Li and Q 9 for 9 Li, respectively. This shows agreement with present literature values but with significantly improved precision. Based on the literature, the quadrupole moment for 8 Li has been re-evaluated to be | Q 8 | = 32.6(5) mb. From this, the quadrupole moment for 9 Li is calculated as | Q 9 | = 31.5(5) mb with the error being dominated by the error of Q 8 . |
