摘要
We measured the high-momentum transfer [Q(2) = 4.8 and 6.2 (GeV/c)(2)] quasi-elastic C-12(p,2p) reaction at theta(cm) similar or equal to 90 degrees for 6 and 7.5 GeV/c incident protons. The momentum components of both outgoing protons and the missing energy and momentum of the proton in the nucleus were measured. We verified the validity of the quasi-elastic picture for ground state momenta up to about 0.5 GeV/c. Transverse and longitudinal momentum distributions of the target proton were measured. They have the same shape with a large momentum tail which is not consistent with independent particle models. We observed that the transverse distribution gets wider as the longitudinal component increases in the beam direction. (C) 1998 Elsevier Science B.V. All rights reserved.
