Abstract

The B10(p,α0)Be7 bare nucleus astrophysical S(E) factor has been measured for the first time at energies from about 100 keV down to about 5 keV by means of the Trojan Horse method (THM). In this energy region, the S(E) factor is strongly dominated by the 8.699 MeV C11 level (Jπ=52+), producing an s-wave resonance centered at about 10 keV in the entrance channel. Up to now, only the high-energy tail of this resonance has been measured, while the low-energy trend is extrapolated from the available direct data. The THM has been applied to the quasifree H2(B10,α0 Be7)n reaction induced at a boron-beam energy of 24.5 MeV. An accurate analysis leads to the determination of the B10(p,α0)Be7 S(E) factor and of the corresponding electron screening potential Ue, thus giving for the first time an independent evaluation of it.
