Abstract
A kinematically complete measurement was made of the Coulomb dissociation o f SE nuclei on a Pb target at 83 MeV/nucleon. The cross section was measure d at low relative energies in order to infer the astrophysical S factor for the Be-7(p, gamma)B-8 reaction. A first-order perturbation theory analysis including El, E2, and M1 transitions was employed to extract the El streng th relevant to neutrino-producing reactions in the solar interior. By fitti ng the measured cross section from E-rel = 130 to 400 keV, we find S-17(0)= 17.8(-1.2)(+1.4) eV b.
