Abstract

An exclusive measurement of the Coulomb breakup of ⁸B into ⁷Be+p at 254 AMeV was used to infer the low-energy ⁷Be(p,γ)⁸B cross section. Particular emphasis was placed on the angular correlations of the breakup particles which demonstrate clearly that E1 multipolarity dominates within the angular cuts selected for the analysis. The deduced astrophysical S₁₇ factors exhibit good agreement with the most recent direct ⁷Be(p,γ)⁸B measurements.
