Abstract
We study the 2γ decays of the light pseudoscalar mesons in a model that allows the isoscalar states to have a significant gluonium component, and show that the rates are in good agreement with experiment. The amount of radial mixing in η,η’ states determines these decays completely. This makes it difficult to test for the presence of gluonium. The radiative decays of ψ’(3685) might be a better way to test for the gluonium admixture. We give estimates for the branching ratios.Keywords
