The exclusive charmonium production process in $ar{p}p$ annihilation with
an associated $pi^0$ meson $ar{p}p o J/psipi^0$ is studied in the
framework of QCD collinear factorization. The feasibility of measuring this
reaction through the $J/psi o e^+e^-$ decay channel with the PANDA
(AntiProton ANnihilation at DArmstadt) experiment is investigated. Simulations
on signal reconstruction efficiency as well as the background rejection from
various sources including the $ar{p}p opi^+pi^-pi^0$ and $ar{p}p o
J/psipi^0pi^0$ reactions are performed with PandaRoot, the simulation and
analysis software framework of the PANDA experiment. It is shown that the
measurement can be done at PANDA with significant constraining power under the
assumption of an integrated luminosity attainable in four to five months of
data taking at the maximum design luminosity.
