Title: Measurement of the π 0 e + e - γ Dalitz decay at the Mainz Microtron

The Dalitz decay π 0 → e +e -γ has been measured in the γp → π 0p reaction with the A2 tagged-photon facility at the Mainz Microtron, MAMI. The value obtained for the slope parameter of the π 0 electromagnetic transition form factor, a π= 0.030 ± 0.010 tot, is in agreement with existing measurements of this decay and with recent theoretical calculations. The uncertainty obtained in the value of a π is lower than in previous results based on the π 0 → e +e -γ decay.
