  We study the annihilation process $p\bar{p} \to \pi^0 e^+ e^-$ within a Regge
framework, as a means to provide constraints on timelike nucleon form factors.
We present results for the $e^+e^-$ angular distributions and the differential
cross sections in kinematics which will be accessible by PANDA@FAIR. To check
the consistency of the model, we first test the approach on the process of real
photon production, $\bar{p} p \to \pi^0 \gamma$, where data in the energy range
of 2.911 GeV$\leq\sqrt{s} \leq 3.686$ GeV exist. We find that a Regge pole
model is able to well reproduce the available data. The analysis is then
extended to a timelike virtual photon in the final state.
