Abstract
- A sample of 3.79 million psi(2S) decays observed in the BES detector is used to study the decays of charmonium to axialvector plus pseudoscalar mesons. The branching fraction for psi(2S) to b1pi agrees with expectations. A contrasting behavior between the psi(2S) and the J/psi decays to K1K cannot be accommodated by an adjustment of the singlet-triplet axialvector mixing angle.<br />7 pages, 3 figures. Changes: excluded one figure, added information, systematic errors increased
