Abstract

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.
