We address the problem of observed charmonium decays which should be forbidden in perturbative QCD. We examine the model in which these decays proceed through a gluonic component of the [ital J]/[psi] and the [eta][sub [ital c]], arising from a mixing of ([ital c[bar c]]) and glueball states. We give some bounds on the values of the mixing angles and propose the study of the [ital p[bar p]][r arrow][phi][phi] reaction at [radical][ital s] [congruent]3 GeV as an independent test of the model.
