dc.descriptionWith the recent investigations of $g^{\ast}g^{\ast}-η^{(\prime)}$ transition form factor and $η-η^{\prime}$ mixing scheme, we present an updated study of the radiative decays $J/Ψ\toη^{(\prime)}γ$ in perturbative QCD. The decays are taken as a test ground for the $g^{\ast}g^{\ast}-η^{(\prime)}$ transition form factors and the $η-η^{\prime}$ mixing scheme. The form factors are found to be working for glunic $η^{(\prime)}$ productions and the mixing angle is constrained to be $ϕ=35.1^{\circ}\pm0.8^{\circ}$.
