- Abstract
- The small-angle elastic scattering for /b pp/ at radic /b s/=23.5, 30.7, and 52.8 GeV and for /b p/ macr /b p/ at radic /b s/=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 (/b pp/ macr )=0.1, the authors obtain sigma /sub tot/(/b p/ macr /b p/)=44.1+/-2.9 mb for the total cross section and /b b/(/b p/ macr /b p/)=13.6+/-2.2 GeV/sup -2/ for the nuclear slope parameter. This supports the dispersion relation prediction that sigma /sub tot/(/b p/ macr /b p/) will start to rise above /b E//sub lab/ ap 200 GeV.
