Abstract:One-proton removal reactions of 936 MeV/u B-8 have been studied with carbon and lead as breakup targets. Using the FRS at GSI, the longitudinal momentum distributions of the Be-7 fragments and the one-proton removal cross section of B-8 were measured. The relative contributions of Be-7 in its ground state and excited state at 429 keV have been determined from measurements of γ rays in coincidence with the fragments from the one-proton removal reaction. The combined data from the two targets allow a determination of the weight of the Be-7*(429) component in the B-8 ground state wave function as (13.3 ± 2.2)%. From this the astrophysical S-17(0) factor is estimated as 19.7 ± 0.5 eV.b.
