Testing Color Evaporation in Photon-Photon Production of $J/\Psi$ at CERN LEP II

The DELPHI Collaboration has recently reported the measurement of J/Psi production in photon-photon collisions at LEP II. These newly available data provide an additional proof of the importance of colored c bar{c} pairs for the production of charmonium because these data can only be explained by co...
