The reactions J/KK»e and J/KK»e have been studied in a sample of 5.8×106 produced J/ decays. The systems K+KS0e and K+K-e0 produced in association with an have enhancements in the mass distribution near 1.44 GeV/c2. The observed angular distributions are consistent with JP=1+ and do not favor a JP=0- assignment. No signal is seen at the nominal f1(1285) mass. The reverse pattern is observed in the KK»e system produced in association with a , which shows an enhancement near 1.280 GeV/c2, and no evidence for structure at 1.4 GeV/c2.
