摘要：

The azimuthal angle distributions of neutral pions at midrapidity from Au+Au reactions at 1 GeV/nucleon incident energy have been measured. An enhanced emission of pi0's perpendicular to the reaction plane is observed. The azimuthal asymmetry is dependent on the pi0 momentum: the pi0 spectrum perpendicular to the reaction plane is harder than in the reaction plane. The strength of the observed asymmetry appears to be more pronounced for pi0 than for charged particles and neutrons.
