In an experiment with the SND detector at the VEPP-2000 e+e- collider, the cross sections for the processes (Formula presented.) were measured at collision energies of √s=1.28-2.00 GeV in the center-of-mass frame. The results agree with the results of earlier measurements in the BABAR experiment and have a commensurate precision.
