Abstract

Polarized ${}^{8}{Li}$ nuclei ( $T_{\frac{1}{2}} = 0.84$ sec), produced in ${}^{7}{Li} (d, p) {}^{8}{Li}$ with polarized deuterons, were implanted in a thick LiI $O_{3}$ crystal used as the target. The asymmetry in the $β$ decay of ${}^{8}{Li}$ was used to detect NMR in a strong magnetic field. About $\frac{1}{3}$ of the ${}^{8}{Li}$ nuclei found Li substitutional sites where the polarization persisted for $T_{1} \approx 11$ sec. The quadrupole moment of ${}^{8}{Li}$ was determined from a knowledge of the electric field gradient in LiI $O_{3}$ .
