Energy- and angle-resolved nuclear reactions, primarily one-nucleon stripping, have been observed for targets of ${\mathrm{CD}}_2$, Be, and C, using a radioactive ${}_{}{}^8{}_{}{}^{}\mathrm{Li}$ beam ($T_{1/2}$=842 ms) at E=14.3 MeV. The ${(}^8$Li${,}^7$Li) neutron transfer reaction populating discrete final states was identified and angular distributions were obtained. This direct-reaction channel has large cross sections (10–100 mb/sr) due, in part, to the unique nuclear properties of ${}_{}{}^8{}_{}{}^{}\mathrm{Li}$. Implications for astrophysical abundances of Li isotopes may be significant.
