Popis:	The production of cc states in two-photon collisions has been studied with the L3 detector at LEP. We present results on the two-photon partial widths for the resonances ηc and χc2, measured at √ ≅ 91 GeV with an integrated luminosity of 140 pb−1 and at √ ≅ 183 GeV with an integrated luminosity of 50 pb−1. The studied decay channels are ηc → 4π, K+K−, π+ π−, K0K∓ π±, π0 K+K−, ηπ+π−, ηlπ+π−, ρρ and gcc2 → J /Ψγ.
