We have measured the dissociation of B-8 in the Coulomb field of Pb-208 at
E-in=51.9 MeV/nucleon and extracted the cross section of the Be-7(p,gamma)B
-8 reaction at 0.4 less than or equal to E-rel less than or equal to 3 MeV,
which is of importance for the B-8 solar-neutrino production rate. The ext
racted astrophysical S-17 factors are consistent with our earlier Coulomb d
issociation measurement, and agree with the values deduced from the direct
capture measurements by Filippone et al., Vaughn et al. and Hammache et al.
The S factor at zero energy wad; extracted to be 18.9+/-1.8 eV-b with the
help of theoretical energy-dependence.
