We have used the N-14(N-12,O-13)C-13 proton transfer reaction at 12 MeV/nucleon to extract the ANC for O-13 -> N-12+p and calculate from it the direct component of the astrophysical S factor of the N-12(p,gamma)O-13 reaction. The optical potentials used and the distorted-wave Born approximation analysis of the proton transfer reaction are discussed. For the entrance channel, the optical potential was inferred from an elastic scattering measurement carried out at the same time as the transfer measurement. From the transfer, we determined the square of the ANC, C-p1/2(2)(O-13(g.s.))=2.53 +/- 0.30 fm(-1), and hence a value of 0.33(4) keV b was obtained for the direct astrophysical S factor at zero energy.
