R-matrix analysis of the 3He(n, p)3H and 7Be(n, p)7Li reactions
- 1. Physique Nucleaire Theorique et Physique Mathematique, CP229 Universite Libre de Bruxelles, B1050 Brussels (Belgium)
Description
We apply the R-matrix formalism to the 3He(n, p)3H and 7Be(n, p)7Li reactions, which play an important role in the big-bang nucleosynthesis. The cross sections are analysed along with the 4He and 8Be spectra near threshold. Neutron and proton widths of high-energy states are determined. A statistical analysis of the uncertainties provide fairly low error bars (typically 2% at the 1σ confidence level) on the reaction rates
