Study of the spectator angle distribution in the dp to ppn reaction at 3.3 GeV/c deuteron momentum

Abstract
The experimental polar angle distribution of the spectator nucleon in the dp to pnp reaction is studied in different intervals of the spectator momentum and four-momentum transfer. The results are compared with those from the impulse model calculations which take account of the ambiguity in the spectator particle identification. Agreement between the calculations and experiment is observed. The final state interaction of two nucleons is also considered.
