摘要：

Branching ratios of J decays into 0, and K*(892)K»+charge conjugate are measured from the 8.6 × 106 J's produced by the DM2 experiment at the Orsay e+e- storage ring DCI. The and mesons are found consistent with a qq» structure and a mixing angle P=(-19.11.4)°. © 1990 The American Physical Society.
