In this paper we report Degenerate Four Wave Mixing ( DFm) experiments on the excitons of GaAs/AlGaAs Multiple Quantum Well (MQW) at high incident intensities. These experiments provide a clear manifestation of Many-Body Interactions (MBI) among the excitons, in the form of a multi-photon (intensity
