The tensor polarization of omega mesons produced in the pd -> He-3 omega reaction has been measured at two energies near threshold. The 3 He nuclei were detected in coincidence with the pi(0)pi(+)pi(-) or pi(0)gamma decay products of the omega. The omega mesons are found to be unpolarised, which is in complete contrast to the case of phi-meson production from the corresponding reaction pd -> He-3 phi. This brings into question the applicability of the Okubo-Zweig-Iizuka rule when comparing the production of vector mesons in low energy hadronic reactions.
