Abstract

We present evidence for the radiative decay J/ with a branching fraction of (1.760.090.45)×10-3. The invariant-mass distribution peaks at 1.8 GeV/c2, just above threshold. Analysis of angular correlations indicates that system below 2 GeV/c2 is predominantly pseudoscalar. Upper limits are presented for the branching fractions of decays of the (1690), the gT states near 2.2 GeV/c2, and the c.
