Abstract

The e+e-→ηπ+π- cross section is measured at the Spherical Neutral Detector (SND) detector in the η decay mode η→3π0. The analysis is based on the data sample with an integrated luminosity of 32.7 pb-1 collected at the VEPP-2000 e+e- collider in the center-of-mass energy range s=1.075-2.000 GeV. The data obtained in the η→3π0 decay mode are found to be in agreement with the previous SND measurements in the η→γγ mode. Therefore the measurements in the two modes are combined.
