英文摘要The electromagnetic transition form factors of eta and eta' are calculated in light-cone perturbation theory. we show that it is unreliable to determine the eta-eta' mixing angle without any additional normalization conditions other than their decay widths to two photons. the possible intrinsic component in the flavor singlet is investigated. the heavy quark pair has distinct properties from the light ones in electromagnetic transition processes of pseudoscalar mesons. it is possible to explore the size of the component and our numerical results disfavor a large portion of the component.
