摘要	Hadronic decays of the P-wave spin-triplet charmonium states chi(cJ)(J=0,1,2) are studied using a sample of psi(2S) decays collected by the BES detector operating at the BEPC storage ring. Branching fractions for the decays chi(cl)-->(KSK+)-K-0 pi(-) + c.c., chi(c0)-->(KSKS0)-K-0, chi(c2)-->(KSKS0)-K-0, chi(c0)-->phi phi, chi(c2)-->phi phi and chi(cJ)-->K+K-K+K- are measured for the first time, and those for chi(cJ)-->pi(+)pi(-)pi(+) pi(-), chi(cJ)-->pi(+)pi(-)K(+)K(-), chi(cJ)--> pi(+) pi(-) and chi(cJ) -->3(pi(+) pi(-)) are measured with improved precision. In addition, we determine the masses of the chi(c0) and eta(c) to be M chi(c0) = 3414.1+/-0.6(stat)+/-0.8(syst) MeV and M eta(c) = 2975.8+/-3.9(stat)+/-1.2(syst) MeV. [S0556-2821(99)01119-4].
