Abstract: We study the reaction mechanism for the correlated $\pi^0\gamma$ emission inthe photon induced reaction on the proton target. Since this reaction isstudied in the GeV region, we assume that it proceeds through the formation ofthe vector meson in the intermediate state. The vector meson, being an unstableparticle, decays into $\pi^0\gamma$ bosons after propagating certain distance.Our analysis shows that the $\pi^0\gamma$ event seen in coincidence in thefinal state dominantly arises due to the decay of $\omega$ meson. Thecalculated results reproduce the measured $\pi^0\gamma$ invariant massdistribution spectra very well.
