摘要：

A beta-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 beta-NQR technique in a zero magnetic field has been applied for the first time to measure the ratio of static nuclear quadrupole moments of Li-8,Li-9, Q(9)/Q(8) = 0.96675(9) denoted by Q(8) for Li-8 and Q(9) for Li-9, respectively. This shows agreement with present literature values but with significantly improved precision. Based on the literature, the quadrupole moment for Li-8 has been re-evaluated to be |Q(8)| = 32.6(5) mb. From this, the quadrupole moment for Li-9 is calculated as |Q(9)| = 31.5(5) mb with the error being dominated by the error of Q(8).
