Sažetak
The astrophysically important 7Li(p,alpha)alpha reaction has been studied via the Trojan horse method in the energy range E = 10400 keV. A new theoretical description, based on the distorted-wave Born approximation approach, allows one to extract information
on the bare astrophysical S-factor, S_b(E), with S_b(0) = 55 ą 3 keV barns. The results are compared with direct experimental data leading to a model-independent value of the electron screening potential energy, U_e = 330 ą 40 eV, much higher than the adiabatic
limit U_ad = 175 eV.
