Antiproton-Proton Ladungsaustausch bei 8 GeV/c

Abstract only given, substantially as follows: An analysis of 7000 of the charge exchange events p+p to n+n at 8 GeV/c is presented. The high angle resolution ( Delta theta <1 mrad) permits an exact investigation of the differential cross section in the vicinity of the forward direction. The pi -...

description Abstract only given, substantially as follows: An analysis of 7000 of the charge exchange events p+p to n+n at 8 GeV/c is presented. The high angle resolution ( Delta theta <1 mrad) permits an exact investigation of the differential cross section in the vicinity of the forward direction. The pi -exchange occurring in this process should produce a structure with a characteristic width Delta t approximately =0.02 (GeV/c)/sup 2/ approximately=m/sup 2//sub pi /; such a structure was observed by J. Angler et al (1971) in the 'line reversed' process p+n to n+p, however the present authors found a nearly flat angular distribution. A phenomenological model is used to compare quantitatively the 2 processes at 8 GeV/c.
