Abstract
As an alternative method to determine the cross section of Be-7 (p, gamma)B -8, the Coulomb dissociation reaction 8B --> (7) Be + p at E-inc = 254 MeV/ u was measured. Our preliminary results show the dominant role of the dipol e excitation in the Coulomb break-up process. The extracted astrophysical S -17 factor is consistent with the lower-value results both of the direct-ca pture studies, and the RIKEN Coulomb-dissociation experiment at similar to 50 MeV/u.
