Abstract
The reaction has been studied at the Cooler Synchrotron COSY-Jülich, using the internal beam and ANKE facility. Total cross sections have been determined at three excess energies near the production threshold. The differential cross section closest to threshold at exhibits a clear wave dominance as well as a noticeable effect due to the proton-proton final-state interaction. Taken together with data for production, a significant enhancement of the ratio of a factor 8 is found compared to predictions based on the Okubo-Zweig-Iizuka rule.
