Abstract：
In this paper we calculate the width of the process J/ψ→γ+ pseudoglueball in perturbative QCD. It is shown that because of the mixture between η、η′ and ι(1440) there is a glueball component in η and η′and it is predominant in the processes J/ψ→γη and γη′. The ratio Γ(J/ψ→γη′)/Γ(J/ψ→γη) obtained in this calculation is bigger than other theoretical models and consistent with experimantal data.
