摘要：
The He-3(a, ? )Be-7 radiative capture reaction has been studied in astrophysical energies to see how Coulomb effects and three-body forces affect calculation uncertainties. For this purpose, the effective field theory (EFT) tool and the Faddeev equation technique were used, and uncertainties for astrophysical S-factor and reaction rate in E-1 and E-2 transitions were determined in sequential steps by including Coulomb interactions and three body forces in the computations. When compared to experimental data, these calculations indicate that the Coulomb effects and three-body forces are corrections for the calculations that help to reduce computational uncertainties.
