Extrapolation of the astrophysical S factor for ^7Be(p,gamma)^8B to solar energies

B. K. Jennings, S. Karataglidis, T. D. Shoppa

We investigate the energy dependence of the astrophysical $S$ factor for the reaction ${}^7$Be$(p,\gamma {)}^8$B, the primary source of high-energy solar neutrinos in the solar $pp$ chain. U…
