Using data consisting of 2.93 fb-1 integrated luminosity at the centre of mass energy √s = 3773 MeV, recorded with the BESIII detector at BEPCII, the cross section and form factor |Fπ|2 was extracted in the energy range 600-900 MeV, using the method of radiative return. The cross section is used as...
