Exact Faddeev-type three-body equations are applied to the study of the proton transfer reactions (d, n) in the system consisting of a nuclear core and two nucleons. The integral equations for the three-body transition operators are solved in the momentum-space framework including the Coulomb interaction via the screening and renormalization method. For a weakly bound final nucleus the calculation of the (d, n) reaction is more demanding in terms of the screening radius as compared to the (d, p) reaction. Well converged differential cross section results are obtained for 7 Be(d, n) 8 B, 12 C(d, n) 13 N, and 16 O(d, n) 17 F reactions. A comparison with the corresponding (d, p) reactions is made. The calculations fail to reproduce the shape of the angular distribution for reactions on 12 C but provide quite successful description for reactions on 16 O, especially for the transfer to the 17 F excited state 1/2 + when using a nonlocal optical potential.
