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