ROLE OF THE PERIPHERAL INTERACTION IN PROTON-PROTON COLLISIONS

It was suggested that the inelastic scattering of any particle on a target nucleon may be dominated by the exchange of one single virtua1 pion. Analysis of experiments showed that there is good evidence for such a mechanism when the incoming particle is a pi meson or a nucleon. The cross section for the process p + p yields p + n + pi /sup +/ was calculated under the assumption of dominating peripheral interaction. The peripheral model agreed well with experimental energy spectra while a statistical spectrum failed to explain the three main features of the distribution: strong peaking at low energy, a broad bump at high energy, and the minimum between them. The total cross section was predicted to be 12 mb and its experimental value was 16.4 plus or minus 0.7 mb. This indicated that something more than the peripheral interaction contributes to the process. (M.C.G.)
