英文摘要The processes psi(2S)-->gammachi(cJ), chi(cJ)-->p(p) over bar $ (J=0,1,2) are studied using a sample of 14x10(6) psi(2S) decays collected with the Beijing Spectrometer at the Beijing Electron-Positron Collider. Very clear chi(c0), chi(c1) and chi(c2) signals are observed, and the branching fractions B(chi(cJ)-->) (J=0,1,2) are determined to be (27.1(-3.9)(+4.3)+/-4.7)x10(-5), (5.7(-1.5)(+1.7)+/-0.9)x10(-5), and (6.5(-2.1)(+2.4)+/-1.0)x10(-5), respectively, where the first errors are statistical and the second are systematic.
