[en] Experimental data obtained in the Neutral Detector at the e⁺e^- storage ring VEPP-2M in the interval of energies 2E from 0.5 to 1.4 GeV have been used to establish for the first time upper limits of the electron widths of the C-even mesons: Γ(eta'→e⁺e^-)<0.06 eV, Γ( f₀(975)→e⁺e^-)<8.4 eV, Γ( f₂(1270)→e⁺e^-)<1.7 eV, Γ( f₀(1300)→e⁺e^-)<20 eV, Γ(a₀(980)→e⁺e^-)xBr(a₀(980)→π⁰eta)<1.5 eV, and Γ(a₂(1320)→e⁺e^-)<25 eV at the 90% confidence level
