摘要The data of radiative decays involving eta, ' and their two-photon decay process and some electromagnetic processes of the J/phi-->P + V (Pseudoscalar and Vector mesons) have been used to study the admixture of pseudoscalar mesons eta, eta' and non-q (q) over bar isoscalar flavor singlet (such as iota/eta (1440)). The mixing parameters of two schemes are fitted by using the method of least squares. If we only consider the mixing of eta and eta' the fitting result is not good. If the admixture of eta, eta' and the non-q (q) over bar mesons (represented by iota later on) has been considered the result is better. The conclusion is that the eta' may contain a few non-q (q) over bar component and iota has some q (q) over bar component.
