| 英文摘要 | The processes psi'-> p (p) over bar pi(0) and psi'-> p(p) over bar eta are studied using a sample of 14x10(6) psi(') decays collected with the beijing spectrometer at the beijing electron-positron collider. the branching fraction of psi'-> p (p) over bar pi(0) is measured with improved precision as (13.2 +/- 1.0 +/- 1.5)x10(-5), and psi'-> p(p) over bar eta is observed for the first time with a branching fraction of (5.8 +/- 1.1 +/- 0.7)x10(-5), where the first errors are statistical and the second ones are systematic. |
