Abstract

The formation of resonances in two-photon interactions has been studied with the L3 detector at LEPl. The two-photon width of the η' has been measured and the form factor obtained measuring the Q² dependence of the formation cross section. The radiative width of the α₂(1320) has been measured and its helicity status determined. The charmonium slate χc2 has been identified and a preliminary value for its two-photon width is given.
