S17 near Zero Energy in a Direct Radiative Capture Analysis
  S17 near zero energy was calculated without using the effective expansion of the S factor or the asymptotic wave functions. Variations of the nuclear potential parameters scarcely affect the d-wave capture cross section below 0.1 MeV, but the s-wave capture cross section near zero energy is affected strongly by the shape of the nuclear potential in our calculations. This result is contrary to the existing assumption that the value of the S factor near zero energy depends on the asymptotic wave function (or asymptotic normalization coefficient). We showed that although the s-wave contribution is dominant near zero energy, the d-wave contribution is not negligible.
