We have measured the Coulomb dissociation of 8B into 7Be and a proton at 254 MeV/nucleon using a large-acceptance focusing spectrometer. The astrophysical S17-factor for the 7Be(p,γ)8B reaction at Ec.m.=0.25-2.78MeV is deduced yielding S17(0)=20.6±1.2 (expt) ±1.0(theor)eVb. This result agrees with the presently adopted zero-energy S17-factor obtained in direct-reaction measurements and with the results of other Coulomb-dissociation studies performed at 46.5 and 51.2 MeV/nucleon.
