FORWARD D(p,2p)n REACTION AT 51.8 MeV

Abstract

Many experimental and theoretical investigations have been made for the D(p, 2p)n reaction at low energies. Most of the works have concerned primarily to the kinematical region, where quasi-free scattering predominates. This chapter presents the results of the measurement on the forward D(p, 2p)n reaction at 51.8 MeV and comparisons with existing theories, particularly with calculations based on the three-body Faddeev formalism. The difference between the calculated values upon off-energy shell amplitudes and on-energy shell amplitudes amounts to more than 30% at 20°–20° and near 60°–60°, where further measurements are desirable. The experiments in a wide angular range, where multiple scattering terms are considered to have important contributions, provide a useful test of the theories. The chapter explains the predicted energy sharing spectra based on the Faddeev formalism with off-energy shell amplitudes at various angles in coplanar symmetric geometry.
