Abstract
The process is studied in the center-of-mass energy region below 2 GeV with the SND detector at the VEPP-2000 collider. The following four intermediate states contribute to this process: , , , and a structureless state. We measure the total cross section and the cross sections for its components: , , and a sum of and the structureless state. Our results are in agreement with previous measurements and have comparable or better accuracies.
