Particularities of neon-22 nuclei inelastic interactions with emulsion at 4.1 A GeV/c

From the analysis of the transverse momentum distribution and azimuthal angle correlations for fragments of the projectile nucleus a residual nucleus of the projectile is shown to acquire a large ∼0.4 GeV/c transverse momentum in collisions of neon-22 nuclei with emulsion. The azimuthal asymmetry for all particles (side-splash) is observed in central collisions with heavy emulsion nuclei. The class of events called particular events where the particles with azimuthal collinearity coefficient β>0.7 are not observed at angle less than (6-12)deg relative to the direction of flight of the projectile, has been also found among the central collision events. The tendency to emission in the opposite direction in the azimuthal plane of colliding nuclear fragments, target nucleus fragments and produced particles is observed. This tendency increases with decreasing an impact parameter. These effects are not described by the cascade-evaporation model
