Elastic scattering and transfer in the ${}^8\mathrm{Li}{+}^{208}\mathrm{Pb}$ system near the Coulomb barrier

The interaction of ${}^8\mathrm{Li}$ with ${}^{208}\mathrm{Pb}$ has been studied over a range of energies near the nominal Coulomb barrier. An excitation function for the total reaction cross section is obtained from elastic-scattering angular distributions and compared with existing data for ${}^{6,7}\mathrm{Li}$ scattering. The result of this comparison indicates that the interaction barrier for ${}^8\mathrm{Li}{+}^{208}\mathrm{Pb}$ is reduced by approximately 4 MeV relative to that of ${}^7\mathrm{Li}.$ The yields of ${}^7\mathrm{Li}$ and ${}^4\mathrm{He}$ from breakup and/or transfer processes are determined, and compared with similar data for other light, weakly bound projectiles.
