    "abstract": "We investigate the energy dependence of the astrophysical S factors for the\nreactions 7Be(p,gamma)8B, the primary source of high-energy solar neutrinos in\nthe solar pp chain, and 16O(p,gamma)17F, an important reaction in the CNO\ncycle. Both of these reactions have predicted S factors which rise at low\nenergies; we find the source of this behavior to be a pole in the S factor at a\ncenter-of-mass energy E = -E_B, the point where the energy of the emitted\nphoton vanishes. The pole arises from a divergence of the radial integrals.",
