Abstract
An exclusive measurement of the Coulomb breakup of into at allowed the study of the angular correlations of the breakup particles. These correlations demonstrate clearly that multipolarity dominates and that multipolarity can be neglected. By using a simple single-particle model for and treating the breakup in first-order perturbation theory, we extract a zero-energy factor of , where the first error is experimental and the second one reflects the theoretical uncertainty in the extrapolation.
