“…[7] rely to some extent on DWBA calculations which, as we have shown, do not account properly for the measured data. Consequently, the experimental data for ͑d , p 0 ͒ and ͑d , n 0 ͒ reactions were not included in our searching procedure, and the spectroscopic factors involved in these transitions were set to unity.…”

“…In this respect we note that the experimental excitation functions for the transfer reactions, in this energy region, exhibit structures which, in principle, could be due to a reminiscent effect of the resonances in the compound nucleus (see, for instance, Ref. [7]). Near these resonances, the meaning and usefulness of the optical model is questionable and all the conclusions reached above can be attributed to an inadequacy of the DWBA calculation.…”

“…2, we present the DWBA-prior calculations for 16 O͑d , n͒ 17 F gs reaction, at two different scattering energies, along with the experimental angular distribution from Ref. [7]. To separate the direct cross section from the compound nucleus component we have considered energy averaged angular distributions.…”

“…To separate the direct cross section from the compound nucleus component we have considered energy averaged angular distributions. The average compound nucleus (CN) contributions for this reaction, estimated by Dietzsch et al [7] are 1.5 mb/ sr for E d = 2.56 MeV and 2.0 mb/ sr for E d = 2.85 MeV. Since this contribution is roughly angular independent, we just added these values to the calculated angular distributions.…”

“…In this paper, we investigate the importance of considering channel couplings effects in the analysis of the 16 O͑d , n͒ 17 F and 16 O͑d , p͒ 17 O transfer reactions, at incident deuteron energies from E d = 2.279 MeV to E d = 3.155 MeV, for which experimental data exist [7]. By performing CRC calculations, we show that if realistic spectroscopic information is to be obtained from these reactions one has to go beyond the Born approximation.…”
