Nuclear collective flow and charged-pion emission in Ne-nucleus collisions at E/A = 800 MeV.
Triple-differential cross sections of charged pions were measured for collisions of Ne projectiles at E/A = 800 MeV with NaF, Nb, and Pb targets.  The reaction plane was estimated event by event from the light-baryon momentum distribution.  For heavy targets, preferential emission of charged pions away from the interaction zone towards the projectile side was observed in the transverse direction.  Such a preferential emission, which is not predicted by cascade calculations, may be attributed to a stronger pion absorption by the heavier spectator remnant.
