| 英文摘要 | A search for radiative decays of the p-wave spin singlet charmonium resonance h(c) is performed based on 4.48 x 10(8) psi' events collected with the besiii detector operating at the bepcii storage ring. events of the reaction channels h(c) -> gamma eta' and gamma eta are observed with a statistical significance of 8.4 sigma and 4.0 sigma, respectively, for the first time. the branching fractions of h(c) -> gamma eta' and h(c) -> gamma eta' are measured to be b(h(c) -> gamma eta') = (1.52 +/- 0.27 +/- 0.29) x 10(-3) and b(h(c) -> gamma eta) = (4.7 +/- 1.5 +/- 1.4) x 10(-4), respectively, where the first errors are statistical and the second are systematic uncertainties. |
