The main features of the C. E. R. N. Intersecting Storage Rings (I. S. R.) are reviewed, together with results obtained in 1971 and 1972 on elastic scattering and total cross-sections. The main result is a 10% increase of the total proton-proton cross-section in the I. S. R. energy range. The simplest picture of high energy proton-proton scattering which emerges from this and the other data, is briefly discussed.

The description of very high energy proton–proton cross-sections in terms of a “black disc” with an “edge” allows a simple generalization to highest energy proton–nucleus cross-sections. This results in a leading ln2W term and a ln W term whose coefficient depends linearly on the radius of the nucleus (W the c.m. energy). The necessary parameters are determined from the fits to p–p data. Since the coefficient of the ln W term is rather large, it is doubtful that the regime of ln2W dominance can be reached with available energies in accelerators or cosmic rays. However, the ln W term can be relevant for highest energy cosmic rays in the atmosphere, where a large increase for the cross-section on nitrogen is expected. Tests of the theory should be possible by studying the coefficient of ln W at p-nucleus colliders.

We study high energy proton-proton (pp) elastic reactions in a meson-exchange model. The observed differential cross sections at small momentum exchanges (|t|<0.8 GeV 2) are well reproduced for a large energy range (s~100 to 1000 GeV 2) in the model. Our study reveals that the meson-exchange model developed in the low and medium energy sector is applicable to the high-energy pp elastic reactions. It might be argued that high-energy reactions at small momentum transfers might be as soft as low and medium energy processes.
