Abstract In this letter, we try to analyze the effects on final pseudoscalar meson η,η' production rates of γ decay produced by pseudoscalar mixing angle, “mass effect” and L = 1 mesons production. If L = 1 mesons production is taken into account, the calculated production rates of η' and η and the ratio between them agree well with ARGUS data at certain mixing angles, otherwise, the data cannot be explained completely. Hence we come to the conclusion that L = 1 mesons production cannot be neglected.
