Abstract: The combination of the photon spectrometer TAPS - an electromagnetic calorimeter with good energy, time and spatial resolution - and the charged particle-detecting KAOS Forward Wall (FW) offers the possibility to study azimuthal distribution of neutral mesons relative to the reaction plane. The experimental data from the Au+Au reaction at 800 MeV were analyzed. The reaction plane was determined on an event by event by event basis and angular distribution of ă.sup.o./sup. and .eta. mesons was reconstructed. The observed elliptic flow signal is negative for .eta. mesons, indicating a preferred emission perpendicular to the reaction plane. The elliptic flow for ă.sup.o./sup. mesons is significantly observed in peripheral Au+Au collisions only.
