    "abstract": "The transfer reaction $^7{\\rm Be(d,n)}^8{\\rm B}$ is modelled for the recent\nlow experimental energies using the DWBA. Tests of the validity of the ANC\nmethod for the extraction of the $S_{17}$ astrophysical factor are performed.\n  We show that a peripheral assumption is no longer accurate for center of mass\nenergies greater than approximately 15 MeV. In all cases we found that core\ndeformation and/or excitation effects to be small as long as the optical\npotential for the entrance channel is not strongly surface peaked. Multistep\ncorrections to the DWBA were found to be small.\n  We also emphasize that the lack of knowledge of the optical potentials for\nthe entrance and outgoing channels induces severe uncertainties in the\nextracted $S_{17}$ astrophysical factor.",
