The result depends on the relative phase between two coupling constants describing $f_1 \\to \\rho^0\\gamma$ decay. The width $\\Gamma (f_1 \\to e^+e^-)$ is estimated to be $\\simeq 0.07-0.19$ eV. Direct $f_1$ production in $e^+e^-$ collisions is discussed, and the $e^+e^- \\to f_1\\to a_0 \\pi \\to \\eta \\pi \\pi$ cross section is calculated. Charge asymmetry in the $e^+e^- \\to \\eta \\pi^+ \\pi^-$ reaction due to interference between $e^+e^- \\to f_1$ and $e^+e^- \\to \\eta \\rho^0$ amplitudes is studied.","authors_text":"A.S.
