Coupled-reaction channels calculations for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$${(}^7$Li${,}^6$Li${)}^{13}$C ${(1/2\mathrm{}}^{+}$, 3.09 MeV) which include the reorientation of ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$, excitation of the ${(1/2\mathrm{}}^{\mathrm{-}}$ 0.48 MeV state of ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$, the transition from this state to the ground state of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$, and transitions between the ground and first excited state of ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ and ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$, are almost identical to finite-range distorted-wave Born approximation calculations, and are highly oscillatory, whereas the data are structureless. These calculations show that multistep processes between ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ and ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ are not responsible for producing the unstructured l=1 transfer measured in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$${(}^7$Li${,}^6$Li${)}^{13}$C ${(1/2\mathrm{}}^{+}$, 3.09 MeV). Data are reported for elastic and inelastic scattering of ${}_{}{}^7{}_{}{}^{}$Li${+}^{16}$O and the single nucleon transfers ${(}^7$Li${,}^6$Li${/}^6$He). Once again, the ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$${(}^7$Li${,}^6$Li${)}^{17}$O ${(1/2\mathrm{}}^{+}$, 0.87 MeV) angular distribution data are structureless, while finite-range distorted-wave Born approximation calculations are highly structured.
