| 英文摘要 | We report first measurements of the branching fractions b(psi(2s)-->gamma eta') = (1.54 +/- 0.31 +/- 0.20) x 10(-4) and b(psi(2s)-->gamma eta) = (0.53 +/- 0.31 +/- 0.08) x 10(-4). the psi(2s) --> gamma eta' result is consistent with expectations of a model that considers the possibility of eta'-eta(c)(2s) mixing. the ratio of the psi(2s)-->gamma eta' and psi(2s)-->gamma eta' rates is used to determine the pseudoscalar octet-singlet mixing angle.
