A sample of J/psi ..-->.. ..mu../sup +/..mu../sup -/ decays produced by a 225-GeV/c ..pi../sup -/ beam on nuclear targets has been analyzed for extra muons. Muons observed in coincidence with J/psi production could indicate either the production of charmed particles or the production of pairs of J/psi particles. We find 90% confidence limits of sigma/sub J/DD-bar/sigma/sub J/<0.016 for associated charm production and sigma/sub J/J/sigma/sub J/<0.005 for the production of J/psi pairs.
