Single π+ Electroproduction at w~2 GeV and the Pion Form Factor

Recently published data on ep-->enπ⁺ near w=2 GeV and 0.0<|k²|<1.0 GeV² are investigated using (i) the model-independent Chew-Low extrapolation technique and (ii) fixed-t dispersion relations. The data are not accurate enough to allow the Chew-Low fit to give an unambiguous determination of F_π. Using fixed-t dispersion relations we obtain F_π(k²)=1(1- k²0.5 GeV²). The effect of resonances other than the P₃₃ is small.
