A comprehensive measurement of the differential cross section for p and pp elastic scattering has been made at large center-of-mass angles. -p and pp scattering were measured with incident laboratory momenta ranging from 2 to 9.5 GeV/c. +p scattering was measured with momenta from 2 to 6.3 GeV/c. Scattering angles were in the range -0.3cos,c.m.0.4. The results of the experiment are compared to constituent models and statistical models.
