The exclusive charmonium production process in $\bar{p}p$ annihilation withan associated $\pi^0$ meson $\bar{p}p\to J/\psi\pi^0$ is studied in theframework of QCD collinear factorization. The feasibility of measuring thisreaction through the $J/\psi\to e^+e^-$ decay channel with the PANDA(AntiProton ANnihilation at DArmstadt) experiment is investigated. Simulationson signal reconstruction efficiency as well as the background rejection fromvarious sources including the $\bar{p}p\to\pi^+\pi^-\pi^0$ and $\bar{p}p\toJ/\psi\pi^0\pi^0$ reactions are performed with PandaRoot, the simulation andanalysis software framework of the PANDA experiment. It is shown that themeasurement can be done at PANDA with significant constraining power under theassumption of an integrated luminosity attainable in four to five months ofdata taking at the maximum design luminosity.
