The 9Be(p,α)6Li and 9Be(p,d)8Be cross sections at low energies

Data for the 9Be(p,α)6Li and 9Be(p,d)8Be reactions with proton energies up to 700 keV are fitted using R-matrix formulae. The data include values of the astrophysical S factors and of the angular-distribution and analysing-power coefficients. A reasonable fit is obtained with two 1- and two 2+ levels of 10B, and one each of 2-, 1+ and 3+ levels. All represent levels outside the energy range fitted except for a 1- level at 6.87 MeV and a 2+ level at 6.95 MeV
