英文摘要	Decays of the j/psi, resonance into the three-photon final state are investigated. branching ratios for the decays of j/psi --> gamma pi(0) and j/psi --> gamma eta' are determined to be br(j/psi --> gamma pi(0)) = (4.6 +/- 1.1) x 10(-5) and br(j/psi --> gamma eta') = (4.12 +/- 0.82) x 10(-3). the ratio of the two decay widths, gamma(j/psi --> gamma eta') / gamma(j/psi --> gamma eta), is 4.79 +/- 0.85. this value agrees well with the predictions of the two theoretical models.
