PACS. 25.70Mn - Projectile and target fragmentation.
The analysis of medium-energy grey protons emitted from ultra-relativistic interactions initiated by - at 60 GeV/nucleon and -AgBr at 200 GeV/nucleon reveals the existence of emission asymmetry in the azimuthal plane which is found to depend on the target excitation but to be nearly independent of projectile mass and energy.
