Charmonium resonance formation in $\gamma\gamma$ collisions with the L3 detector
Measurements of the two-photon partial widths of the charmonium mesons chi /sub c2/ and eta /sub c/ from data collected by the L3 detector are presented. The data comprises 140 pb/sup -1/ at square root (s) approximately=91 GeV and 52 pb/sup -1/ at square root (s) approximately=183 GeV. The Q/sup 2/...
