Abstract
The results of a nonrelativistic calculation of the exclusive (p,2p)n cross section and inclusive (d→,p)X cross section and tensor analyzing power , based on an expansion of the scattering τ matrix up to double scattering, are presented. Five different wave functions, including Reid with soft core, Paris, Bonn, Amsterdam, and Moscow, as well as two NN phase-shift amplitude sets, VPI and Saclay-Geneva, are used. Detailed comparison with the data available indicates that double scattering is indeed important for both reaction channels. For (p,2p) the complete calculation removes a discrepancy of a factor of 2 to 8 present if comparison is made with the impulse approximation only; the Paris wave function gives the best results. For (d→,p) the complete calculation results agree fairly well with both cross section and data up to q=200 MeV/c. However, neither an enhancement in σ, nor an abrupt turn toward less negative values, both occurring for q>250 MeV/c, can be explained by the present calculation. Neither the wave functions nor the NN amplitudes used are Lorentz invariant, but the kinematics is treated relativistically. Possible causes for the discrepancy are briefly discussed.
