摘要 | The decays of J/psi and psi(2S) to nK(S)(0) (Lambda) over bar + c.c. are observed and measured for the first time, and the perturbative QCD "12%" rule is tested, based on 5.8 x 10(7) J/psi and 1.4 x 10(7) psi(2S) events collected with BESII detector at the Beijing Electron-Positron Collider. No obvious enhancement near n (Lambda) over bar threshold in J/psi -> nK(S)(0)(Lambda) over bar + c.c. is observed, and the upper limit on the branching ratio of J/psi -> (KSX)-X-0, X -> n (Lambda) over bar is determined.
