Abstract

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 E^c.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.
