We have measured total cross sections for p-p scattering with the results σT=40.42±0.27 mb at 200 GeV/c and 40.40 ± 0.28 mb at 300 GeV/c. Our 300-GeV/c result is significantly higher than published data from the CERN intersecting storage rings. Our data, taken together with the Serpukhov data, indicate that the cross section rises ≅ 2 mb between 60 and 250 GeV. The variation of the cross section with energy may be more complicated than the a+blnαs behavior commonly assumed for Elab≳50 GeV.
