Title: How Accurately Do We Know the Cross Section of the 7Be(p, {gamma})8B Reaction?

Abstract

The 'world average' of the astrophysical cross section factor , S17(0), is driven by the Seattle result due to the very small quoted uncertainty, which we however demonstrate it to be an overestimated accuracy. We propose more realistic error bars for the Seattle results based on the published Seattle data. This leads to a an uncertainty of the measured slope of S17 and thus an uncertainty due to extrapolation that can be reasonably estimated to be {sub -3.0}{sup +0.0} eV-b.

  • Nuclear structure of {sup 7}Be, {sup 8}B and {sup 7,8}Li is studied within the ab initio no-core shell model (NCSM). Starting from the high-precision CD-Bonn 2000 nucleon-nucleon (NN) interaction, wave functions of {sup 7}Be and {sup 8}B bound states are obtained in basis spaces up to 10{h_bar}{Omega} and used to calculate channel cluster form factors (overlap integrals) of the {sup 8}B ground state with {sup 7}Be+p. Due to the use of the harmonic oscillator (HO) basis, the overlap integrals have incorrect asymptotic properties. We fix this problem in two alternative ways. First, by a Woods-Saxon (WS) potential solution fit tomore » the interior of the NCSM overlap integrals. Second, by a direct matching with the Whittaker function. The corrected overlap integrals are then used for the {sup 7}Be(p,{gamma}){sup 8}B S-factor calculation. We study the convergence of the S-factor with respect to the NCSM HO frequency and the model space size. Our S-factor results are in agreement with recent direct measurement data.« less

We also test the spectroscopic factors and the corrected overlap integrals from the NCSM in describing the momentum distributions in knockout reactions with {sup 8}B projectiles. A good agreement with the available experimental data is also found, attesting the overall consistency of the calculations.« less
  • It is argued that the soils information the authors have available to apply to environmental issues has depended on the kinds of questions they have asked in soil science. Four periods are identified in the last 150 yr when they asked different kinds of questions. The last period brings the authors back to some of the same questions asked in the first period. The characteristics of these periods are discussed to give them a perspective as their thinking is now changing from soils as an input into crop production to include a greater emphasis on soil processes that mediate globalmore » changes.« less
  • The (7Li,7Be) charge-exchange spin-flip reaction was for the first time used to deduce the distribution of the B(M1) reduced matrix elements for the photodisintegration of deuteron from the analogous B(GT) distribution. The obtained distribution is in agreement with recent photodisintegration measurements and effective-field calculations.
