The single-proton pickup reactions /sup 40/Ca(/sup 11/B,/sup 12/C)/sup 39/K and /sup 40/Ca(/sup 13/C,/sup 14/N)/sup 39/K are found to produce qualitatively different angular distributions when compared at similar bombarding energies. The surface transparent potential invoked to explain the forward rise in the /sup 40/Ca(/sup 13/C,/sup 14/N)/sup 39/K differential cross section at 40 MeV is shown to be inappropriate for the /sup 40/Ca(/sup 11/B,/sup 12/C)/sup 39/K data analysis at 32 MeV incident energy. For the higher energy measurements at 68 MeV, both systems produce oscillatory angular distributions, but in the former case the distorted-wave Born approximation prediction is out of phase with the data, while in the latter it is exactly in phase with the data. The success of the distorted-wave Born approximation in predicting the magnitude of the cross sections is also different in the two cases.
