The results of the search for the e^+e^-^ process in the center-of-mass energy range from 1. 075 to 2 GeV are presented. We analyze data with an integral luminosity of 746 pb^-1 accumulated with the SND detector at the e^+e^- collider VEPP-2000 in 2010--2024. The ^⁰⁰ decay is used in the analysis, with the subsequent and ⁰ decays into. Upper limits not exceeding 13 pb have been set on the e^+e^-^ cross section at the 90\% confidence level.
