Measurement of the Cross Section for the Process with the SND Detector

The process was studied in the energy range between 1 and 2 GeV to the best precision in the world. The data used correspond to an integrated luminosity of accumulated with the SND detector at the VEPP-2000 collider. The statistical accuracy of the measured cross section is 2 to 22 , whereas the sys...

Zusammenfassung:	The process was studied in the energy range between 1 and 2 GeV to the best precision in the world. The data used correspond to an integrated luminosity of accumulated with the SND detector at the VEPP-2000 collider. The statistical accuracy of the measured cross section is 2 to 22 , whereas the systematic uncertainty is 2.6 to 14 . The present results agree with the results of earlier measurements but have a better precision.
