| Sumario: | This presentation reviews the progress made since the photon '97 conference on the measurements of charmonium states in photon-photon collisions at LEP. New measurements on chi /sub c2/-formation are reported by the OPAL and L3 collaborations. New results on eta /sub c / formation, in particular a first measurement of the form factor are presented by L3. The DELPHI and L3 experiments give new limits on eta /sub c/' formation. (17 refs). |
