We report a measurement of the proton-antiproton total cross section σT at c.m.s. energies √s =546 and 1800 GeV. Using the luminosity-independent method, we find σT=61.26±0.93 mb at √s =546 GeV and 80.03±2.24 mb at √s =1800 GeV. In this energy range, the ratio σel/σT increases from 0.210±0.002 to 0.246±0.004.

Measurement of the anti-p p total cross-section at S**(1/2) = 1800-GeV

The pp differential elastic scattering cross section was measured at √s = 1800 GeV, using an improved accelerator luminositydetermination and CDF small angle data in the range of 0.05 ≤ t ≤ 0.2(GeV/c)2. By extrapolating the differential cross sections to t=0 and using the optical theorem we obtain a total cross section of σtot(pp) = 72.0±3.6 mb. This result is preliminary in the sense that we expect to further reduce the systematic error on the optical point.
