Abstract

The 3He(α,γ)7Beradiativecapturereaction has been studied in astrophysicalenergies to see howCoulomb effectsand three-body forcesaffect calculation uncertainties. For this purpose, theeffectivefield theory (EFT) tooland the Faddeev equation techniquewere used,and uncertainties forastrophysical S-factorand reaction ratein E1 and E2 transitions were determined in sequentialsteps by includingCoulomb interactionsand three-body forces in thecomputations. When compared to experimental data, thesecalculations indicatethat theCoulomb effectsand three-body forcesarecorrections for thecalculations that help to reducecomputational uncertainties.
