Abstract: Based on the branching ratios of ψ(2S)→VP given by the BES collaboration, we make a new analysis to study the mixing of pseudoscalars. The mixing angle of η and ηp, θp is determined to be (-7.54±1.52)° which is consistent with the value obtained from quadratic Gell-Mann-Okubo formula. From this work we also know that the strength of DOZI to SOZI is about 14% in ψ(2S)→VP, and the phase angle of electromagnetic amplitude to strong amplitude is (156±89)°.
