Abstract: A detailed comparison of the available experimental data on the triply differential cross sections for π+ mesons produced in the reaction pp→npπ+ at initial proton energies ~660, 730, 800, 991, and 1000 MeV is performed using an improved version of the one-pion exchange model for this reaction. The model rigorously takes into account the contributions of four Feynman pole diagrams and all their interference terms in the approximation of the 3,3 resonance for the πN virtual scattering amplitude. The applicability of the model within the ~10-15% accuracy is demonstrated and a pion-nucleon form factor is extracted.
