The reactions Mg26(O16, N15)Al27 and Si30(O16, N15)P31 have been studied at an O16 beam energy of 42 MeV. Spectroscopic factors for all observed transitions have been extracted using the no-recoil distorted-wave Born approximation. For J=52+ and 12+ states, the relative spectroscopic factors agree well with those derived from (He3,d) studies. For J=32+ states, the (O16, N15) spectroscopic factors disagree by a factor of 5 with those derived from (He3,d) studies. As suggested by Kovar et al., this may be a result of neglecting recoil effects. The above factor of 5 discrepancies are of the same order as those noted 40 MeV above the Coulomb barrier by Kovar et al.
