We present an analysis of the decay J/'4 in the final states +-+- and +0-0. The branching fractions obtained are B(J)= (3.05±0.08±0.45) ×10-3 and B(J/+0-o)= (8.3±0.2±3.1)×10-3 for m4 less than 2 GeV/c2. The 4 invariant-mass distributions extend from 1.0 to 3.0 GeV/c2, showing peaks at approximately 1.55 and 1.8 GeV/c2. In an analysis of the 4 final state we find that 50% of the events below 2 GeV/c2 are pseudoscalar, the product branching fraction of which is determined to be &)= (4.7±0.3±0.9)×10-3. No other significant component is found, and upper limits on the product branching fraction B(J/X)B(X) are presented for the theta(1690) and the gT states near 2.2 GeV/c2.
