Abstract
The average polarization of the produced in the reaction has been measured between center-of-mass angles 134° and 166° for an incident momentum of 1145 MeV/c. A polarized proton target was used, and the polarization was found by measuring the difference in the production rate of mesons for protons polarized along the production-plane normal and against it. Spark chambers were used to record the and trajectories, and the momentum was obtained from a magnetic spectrometer while the momentum was obtained from a range telescope. Each event was kinematically reconstructed in a one-constraint fit to help eliminate events produced from protons bound in heavy nuclei of the target. The polarization was found to be -0.36±0.46.
