New, accurate data are presented on the near threshold p(e,e'p)pi^0 reactionin the range of four-momentum transfers between Q^2=0.05 and 0.15GeV^2/c^2. Thedata were taken with the spectrometer setup of the A1 Collaboration at theMainz Microtron MAMI. The complete center of mass solid angle was covered up toa center of mass energy of 4MeV above threshold. These results supersede theprevious analysis based on three separate experiments, and are compared withcalculations in Heavy Baryon Chiral Perturbation Theory and withphenomenological models.

Consistent threshold pi0 electro-production at Q^2=0.05, 0.10, and 0.15 GeV^2/c^2
