Energy Dependence of the Proton-Proton Total Cross Section for Center-of-Mass Energies Between 23 and 53 GeV
Phys. Lett. 44B (1973) 112;

Abstracts
Measurements of proton-proton elastic scattering at angles around 6 mrad have been made at centre-of-mass energies of 23, 31, 45 and 53 GeV using the CERN Intersecting Storage Rings. The absolute scale of the cross section was established by determination of the effective density of the colliding beams in their overlap region. Proton-proton total cross sections were deduced by extrapolation of the elastic differential cross section to the forward direction and by application of the optical theorem. The results indicate that over the energy range studied the proton-proton total cross section increases from about 39 to about 43 mb.
