COULOMB DISSOCIATION OF B-8 AND THE BE-7(P, GAMMA)B-8 REACTION AT LOWENERGIES

The cross section for Coulomb dissociation of B-8-the Pb-208(B-8,Be-7 p)Pb-208 reaction-was measured using a B-8 radioactive beam of 46.5 Me V/nucleon energy, and the cross section for the Be-7(p, gamma)B-8 capt ure reaction was deduced at low energies; E(c.m.) = 0.6 - 1.7 MeV. The extracted astrophysical S-17 factors were found to be consistent with the values measured by Vaughn et al, and Filippone et al. This result encourages further experimental studies extended to lower relative en ergies for a new determination of the S-17 value relevant to the B-8 s olar neutrino flux.
