英文摘要Decays of the psi(2S) into vector plus pseudoscalar meson final states have been studied with 14x10(6) psi(2S) events collected with the BESII detector. Branching fractions of psi(2S)-->phieta, phieta('), and omegaeta('), and upper limits of psi(2S)-->phipi(0) and omegaeta are obtained: B(psi(2S)-->phieta)=(3.3+/-1.1+/-0.5)x10(-5), B(psi(2S)-->phieta('))=(3.1+/-1.4+/-0.7)x10(-5), and B(psi(2S)-->omegaeta')=(3.2(-2.0)(+2.4)+/-0.7)x10(-5); and B(psi(2S)-->phipi(0))<0.40x10(-5), and B(psi(2S)-->omegaeta)<3.1x10(-5) at the 90% C.L. These results are used to test the perturbative QCD "12% rule."
