Indirect measurements of the solar-neutrino production reaction Be-7(p, gamma)B-8

Low-energy cross sections of the Be-7(p, gamma)B-8 reaction is of crucial i mportance, because they determine the high-energy solar neutrino flux. Coul omb dissociation with intermediate-energy B-8 beams and low-energy proton-t ransfer reactions with Be-7 beams have been investigated to determine indir ectly the astrophysical S-17 factors of the Be-7(p, gamma)B-8 reaction. The results of these studies are generally in good agreement with the ones obt ained by direct capture measurements using intense proton beams and radioac tive Be-7 targets.
