Abstract

The reaction e/sup +/e/sup -/->e/sup +/e/sup -/A/sub 2/(1320) has been observed by detecting the decay A/sub 2/->..pi../sup +/..pi../sup -/..pi../sup 0/. The two-photon width of the A/sub 2/ has been measured to be GAMMA(A/sub 2/->..gamma gamma..) = (0.90 +- 0.27 (stat.) +- 0.16 (syst.)) keV. The cross section sigma(..gamma gamma..->..pi../sup +/..pi../sup -/..pi../sup 0/) has been determined outside the A/sub 2/ resonance region.
