Abstract：
With the recent investigations of the g^*g^*-η^(') transition form factor and η-η^' mixing scheme, we present an updated study of the radiative decays J/ψ → η^(')γ in perturbative QCD. The decays are taken as a test ground for the g^*g^*-η^(') transition form factors and the η-η^' mixing scheme. The form factors are found to be working for glunic η^' production and the mixing angle is constrained to be φ=35.1°±0.8°.
