Measurement of the e e → ηππ cross section in the $$ \sqrt s $$ = 1.04-1.38-GeV energy range with a spherical neutral detector at the VEPP-2M collider.

The e e → ηππ cross section in the η → 2γ channel has been measured in the $$ \sqrt s $$ = 1.04- to 1.38-GeV energy range. The data with a total integrated luminosity of 9.05 pb 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. [ABSTRACT FROM AUTHOR]
