Production of polarizedLi8with theLi7(d→,8Li→)p reaction

The polarization transferred to ${}_{}{}^8{}_{}{}^{}\mathrm{Li}$ in the ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$(d→${,}^8$Li→)p reaction was measured for transverse and, for the first time, longitudinal polarized deuteron beams with energies between 1.5 and 10 MeV. Enriched ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ metallic targets, sufficiently thick to stop the incident beam and all recoils, were used. The longitudinal polarization transfer coefficient is nearly constant over this energy range, with $K_z^z$=0.239±0.005. For deuteron energies above 2.5 MeV, the transverse polarization transfer coefficient is slowly decreasing, with average value $K_y^y$=0.221±0.008. Below 2.5 MeV deuteron energy, $K_y^y$ increases markedly, reaching $K_y^y$=0.31 at $E_d$=1.5 MeV. The polarization relaxation time, $T_1$=(2.87±0.08) s, and the half-life, $t_{1/2}$=(0.838±0.009) s, are in good agreement with prior work.
