Abstract

The ¹⁰B(p,α0)⁷Be reaction has been studied by applying the Trojan Horse method to the 2H(¹⁰B,α0 ⁷Be)n reaction. The bare-nucleus astrophysical S(E)-factor in absolute units was extracted in a wide energy range, from 2.2 MeV to 3 keV and normalized to the direct experimental data, thus allowing determination of the electron screening potential for which a value of U_e=391±74 eV was obtained.
