Breakup cross sections of are analyzed in a two-body structure model, with an inert core and a loosely bound valence proton. The nuclear induced breakup is calculated in an eikonal approximation, and Coulomb dissociation is calculated to first order. There is a strong correlation within this model between the total strength and the one-proton removal cross section Thus we find that the measured values of for a carbon target are consistent with the strength extracted in recent Coulomb dissociation experiments. The predicted values on high- targets are significantly larger than measured. We discuss how this discrepancy can be reduced by improving the description of Coulomb dissociation.
