Abstract

A study of resonance formation is presented in the pi(+)pi(-)pi(0) final state in two-photon collisions at LEP. The alpha(2)(1320) radiative width is measured to be Gamma(eta) = 0.98 +/- 0.05 +/- 0.09 keV. The helicity 2 production is dominant. Exclusive pi(+)pi(-)pi(0) production has also been studied in the mass region above the alpha(2) in the rho pi and f(2) pi channels. This region is dominated by a J(P) = 2(+) helicity 2 wave.
