A clear, prompt dimuon signal has been observed in a low-statistics streamer-chamber experiment with 16-GeV/c ..pi..p interactions. The good mass resolution makes it possible to identify the contributions from rho and ..omega.. decays and eta and ..omega.. Dalitz decays. An excess of events is observed in the mass region approx.400-600 MeV which is not accounted for by the above-mentioned decays.
