Abstract
Cross sections and analyzing powers for are presented. A shoulder in the cross section previously reported at higher energies and for carbon is observed for H, C, and Ti at the same -c.m.-frame proton momentum, GeV/c. At GeV/c both cross-section and data depend only weakly upon the target atomic number . Calculations in the plane-wave impulse approximation with several wave functions, and with either a or a six-quark component added, are discussed.
