The e+e- → ηπ+π- cross section in the η → 2γ channel has been measured in the √S = 1.04- to 1.38-GeV energy range. The data with a total integrated luminosity of 9.05 pb-1 were collected on a spherical neutral detector at the VEPP-2M collider. The results are consistent with the BaBar and CMD2 data and have a higher statistical accuracy. © 2010 Pleiades Publishing, Ltd.
