Coupled reaction channels calculations were performed for the 16O(d,n)17F and 16O(d,p)17O transfer reactions for the ground and first excited states at several energies from Elab=2.29 MeV up to 3.27 MeV. A strong polarization effect between the entrance channel and the transfer, 16O(d,n)17F (1/2+,0.495) and 16O(d,n)17O (1/2+0.87), channels was observed. This polarization effect had to be taken into account to all orders for obtaining realistic spectroscopic factors from these reactions. The 16O(p,{gamma})17F and 16O(n,{gamma})17O direct captures were calculated using the Asymptotic Normalization Coefficients (ANC) values from these transfer reactions analysis. The astrophysical S-factors were compared to measurements. The Maxwellian-averaged neutron capture cross section at kT=30 keV was 22(3){mu}barn.
