摘要
We apply the R-matrix formalism to the He-3(n, p)H-3 and Be-7(n, p)Li-7 reactions, which play an important role in the big-bang nucleosynthesis. The cross sections are analysed along with the He-4 and Be-8 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 1sigma confidence level) on the reaction rates.
