A search for direct production of C-even resonances a2(1320) and f2(1270) in e+e- annihilation was performed with SND detector at VEPP-2M e+e- collider. The upper limits of electronic widths of these mesons were obtained at 90% confidence level: Γ(a2(1320) → e+e-) < 0.56 eV, Γ(f2(1270) → e+e-) < 0.11 eV. (C) 2000 Published by Elsevier Science B.V.
