Abstract
A sample of 3.79 X 10(6) psi(2S) events is used to study the decays of char monium to axial-vector plus pseudoscalar mesons. The branching fraction for the decay psi(2S) --> b(1)(+/-) (1235)pi(-/+) agrees with expectations bas ed on scaling the corresponding J/psi branching fraction. Flavor-SU(3)-viol ating K-1(1270)-K-1(1400) asymmetries with opposite character for psi(2S) a nd J/psi decays are observed. This contrasting behavior cannot be accommoda ted by adjustments of the singlet-triplet mixing angle.
