Study of the proton-deuteron break-up reaction in complete kinematics at 1 GeV

Abstract The coincidence cross section and polarization have been measured for the proton-deuteron break-up reaction pD→ppn at 1 GeV in a kinematically complete experiment. Two final protons from the reaction were detected in coincidence by means of a two-arm spectrometer at non-symmetric scattering angles θ 1 =19°–27°, θ 2 =61° in the momentum range of the neutron-spectator up to 0.3 GeV/ c . At kinematic conditions of the experiment the coincidence cross section is well described in the framework of the single scattering impulse approximation with the Paris wave function of the deuteron. The polarization is also in good agreement with IA predictions.
