Abstract
Intense spectator-proton peaks were observed in the reaction . Their shapes were well fitted by plane-wave Born-approximation calculations, assuming either knockout or quasielastic scattering accompanied by charge exchange to be the mechanism. Their intensities relative to the quasielastic peaks from were correctly predicted by charge-exchange calculations, but only when an unrealistic mixture of exchange forces was used. All direct knockout calculations gave relative intensities at least ten times too small.
