Samples of the reaction p/sub arrow-up/ p..-->..p..omega..p, consisting of 20 000 and 1000 events at 11.75 and 6 GeV/c, respectively, were obtained using the Zero Gradient Synchrotron polarized proton beam and the Effective Mass Spectrometer. A narrow enhancement near threshold is seen in the ..omega..p mass distribution. The t distribution of this enhancement shows a pronounced dip near t = -0.2 GeV/sup 2/ at both beam momenta, suggesting that ..omega.. exchange is the dominant production mechanism. The joint-decay-angular-distribution moments and polarization correlations have been determined as functions of ..omega..p mass. Amplitude analysis of these moments indicates that the low-mass enhancement is due to the high-mass tails of spin-parity 3/2/sup -/ and 3/2/sup +/ states below ..omega..p thresholds. Polarization correlations consistent with zero provide evidence for the lack of resonant behavior in the low-mass enhancement itself.
