From a study of the correlation of the longitudinal momenta of final-state nucleons in pd collisions, a classification of the event types has been effected. The event types identified are quasi-elastic (peripheral), central and charge-exchange collisions. Using the Van Hove LPS plot it is observed that those events classified as quasi-elastic are dominant and the nucleons resulting from the deuteron break-up in these collisions have approximately equal momenta. The quasi-elastic and the elastic events have been compared with the Glauber multiple scattering theory and are found to be well described by the model for small-angle scattering.
