| 英文摘要 | Based on the branching ratios of psi(2S) -> VP given by the BES collaboration, we make a new analysis to study the mixing of pseudoscalars. The mixing angle of eta and eta(p)', theta(p) is determined to be (-7.54 +/- 1.52)degrees 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 psi(2S) -> VP, and the phase angle of electromagnetic amplitude to strong amplitude is (156 89)degrees. |
