Abstract

Intense spectator-proton peaks were observed in the reaction D(He3,tp)p. Their shapes were well fitted by plane-wave Born-approximation calculations, assuming either knockout or He3n quasielastic scattering accompanied by charge exchange to be the mechanism. Their intensities relative to the quasielastic peaks from D(He3,He3p)n 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.
