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