Astrophysical S factor for 9Be(p, )10B Academic Article uri icon

abstract

  • The 9Be(p, )10B reaction plays an important role in primordial and stellar nucleosynthesis of light elements in the p shell, but the energy dependence of S(E) has not been well understood. We reanalyze the existing 9Be(p, )10B experimental data within the framework of the R-matrix method. The direct capture part of the S factor is calculated using the experimentally measured asymptotic normalization coefficients for 10B9Be + p. The fitted parameters of the low-lying 10B resonances are also required to be consistent with previous measurements of 6Li(, )10B. A good simultaneous fit to both radiative capture reactions is found, in contrast to previous analyses. These results demonstrate that experimentally measured asymptotic normalization coefficients, coupled to the R-matrix method, can provide a reasonable determination of direct radiative capture rates, even when the captured proton is tightly bound in the final nucleus.
