Abstract
interactions were studied at an incident momentum of 5.5 GeV/c in a 5-eV/μb exposure of the 30-in. deuterium bubble chamber at the Argonne Zero-Gradient Synchrotron. The dominant feature of the reaction is production, although the low-mass enhancement, usually referred to as , is also prominent in the mass spectrum. The low momentum transfer to the deuteron imposed by coherent production strongly favors a mass in the region of the enhancement. As is usually observed, the production and decay characteristics of the system are generally compatible with a spin-parity assignment. A study of the system reveals an -wave--wave interference similar to that observed in scattering. The data are compared with the predictions of a double-Regge-pole model.
