A016200100030 COMMENT - by authors - abstract: A016200100031 The Coulomb dissociation of 8-B into 7Be and a proton A016200100032 at 254 MeV/nucleon using a large-acceptance focusing A016200100033 spectrometer was measured. The astrophysical A016200100034 S17-factor for the 7-Be(p,g)8-B reaction at A016200100035 E-cm=0.25 - 2.78 MeV is deduced yielding A016200100036 S17(0)=20.6+-1.2 (Expt)+-1.0(Theor) eV*B. This A016200100037 result agrees with the presently adopted zero-energy A016200100038 S17-factor obtained in direct-reaction measurements andA016200100039 with the results of other Coulomb-dissociation studiesA016200100040 performed at 46.5 and 51.2 MeV/nucleon.
