A study of resonance formation is presented in the π⁺ π^- π⁰ final state in two-photon collisions at LEP. The a₂(1320) radiative width is measured to be Γγγ = 0.98 ± 0.05 ± 0.09 keV. The helicity 2 production is dominant. Exclusive π⁺ π^- π⁰ production has also been studied in the mass region above the a₂ in the pπ and f₂π channels. This region is dominated by a J^P = 2⁺ helicity 2 wave.Facultad de Ciencias Exactas
