As an alternative method to determine the cross section of 7Be (p, γ)8B, the Coulomb dissociation reaction 8B →7 Be + p at Einc = 254 MeV/u was measured. Our preliminary results show the dominant role of the dipole excitation in the Coulomb break-up process. The extracted astrophysical S17 factor is consistent with the lower-value results both of the direct-capture studies, and the RIKEN Coulomb-dissociation experiment at ∼50 MeV/u.
