Elastic scattering for /sup 16/O on /sup 208/Pb and the single-nucleon transfer reactions /sup 208/Pb(/sup 16/O,/sup 15/N) /sup 209/Bi and /sup 208/Pb(/sup 16/O,/sup 17/O) /sup 207/Pb have been measured at bombarding energies of 104, 138.5, and 216.6 MeV. A detailed optical model analysis of /sup 16/O on /sup 208/Pb elastic data from 80 to 216.6 MeV has been made. The Woods-Saxon potential parameters must be energy dependent to accurately reproduce the elastic data. Finite-range distorted-wave Born-approximation calculations employing both energy- independent and energy-dependent optical potentials are compared with the transfer data. With the exception of small shifts in angle, the distorted-wave Born approximation correctly predicts the shape of the angular distributions and the evolution of the relative single-particle strengths as functions of the bombarding energy. However, the distorted-wave Born approximation fails (by a factor of 2 to 3) to predict the observed energy dependence of the absolute single-particle transfer strength. It is demonstrated that this failure is not likely to be corrected by changes in the bound-state or optical-model potentials, if Woods-Saxon forms that fit the elastic data are used.
