摘      要：The momentum distribution of forward protons from relativistic collisions of deutrons with nuclei is computed from a Glauber theoretical ansatz of Bertocchi and Tékou. In this paper we approximate the outgoing proton-neutron scattering state (disintegrated deuteron) with a plane wave minus the component of this plane wave along the deuteron bound state vector. With no fitted parameters we find good agreement with data from the reaction d+C12→p+X in the region corresponding to non-relativistic Fermi momenta in the forward direction. At more relativistic Fermi momenta, the model deviates more from the data, which can be due to an incorrect choice of the short distance part of the deuteron wave function as well as to off-shell effects in the deuteron. © 1978.
