Abstract: (APS)

The process e+e-→π0γ is studied with the SND detector at the VEPP-2000 e+e- collider. Basing on data with an integrated luminosity of 41 pb-1 recorded in 2010-2012 we measure the e+e-→π0γ cross section in the center-of-mass energy range from 1.075 up to 2 GeV. In the range 1.4–2.0 GeV the process e+e-→π0γ is studied for the first time.
