摘要

A study of resonance formation is presented in the + 0 nal state in twophoton collisions at LEP. The a2(1320) radiative width is measured to be = 0:98 0:05 0:09 keV. The helicity 2 production is dominant. Exclusive + 0 production has also been studied in the mass region above the a2 in the and f2 channels. This region is dominated by a J=2 helicity 2 wave.
