【 摘 要 】

𝜋0 𝛾 invariant mass distribution spectrum has been calculated for the (𝛾, 𝜋0 𝛾) reaction on 12C nucleus at 2.5 GeV beam energy. These 𝜋0 and 𝛾 are assumed to originate due to the decay of vector mesons produced in the photonuclear reaction. The nuclear medium effect on vector mesons and the effect of 𝜋0 rescattering on the 𝜋0 𝛾 invariant mass spectrum have been investigated.
