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°.
