摘要：

A search for direct production of C-even resonances a(2)(1320) and f(2)(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: Gamma (a(2)(1320) --> e(+)e(-)) < 0.56 eV, <Gamma>(f(2)(1270) --> e(+)e(-)) < 0.11 eV.
