Description
The small-angle elastic scattering for pp at √s-bar = 23.5, 30.7, and 52.8 GeV and for p-barp at √s-bar = 52.8 GeV are measured. The data are normalized on Coulomb scattering. Using the optical theorem and the best estimate of the real part of the forward scattering amplitude, rho(pp-bar) = 0.1, we obtain sigma/sub tot/(p-barp) = 44.1 +- 2.9 mb for the total cross section and b(p-barp) = 13.6 +- 2.2 GeV-2 for the nuclear slope parameter. This supports the dispersion relation prediction that sigma/sub tot/(p-barp) will start to rise above E/sub lab/roughly-equal200 GeV
