| الوصف: | The production of omega mesons in the pd -> He-3 omega reaction has been studied at two energies near the kinematic threshold, T-p = 1450 MeV and T-p = 1360 MeV. The differential cross section was measured as a function of the omega c.m. angle at both energies over the whole angular range. Whereas the results at 1360 MeV are consistent with isotropy, strong rises are observed near both the forward and backward directions at 1450 MeV. Calculations made using a two-step model with an intermediate pion fail to reproduce the shapes of the measured angular distributions and also underestimate the total cross sections. ; We wish to thank the personnel at the The Svedberg Laboratory for their support during the course of the experiment. We are grateful to Y. le Bornec for providing us with information regarding Ref. [5] and also V. Shklyar for supplying the t-matrix element of the Giessen model described in Ref. [31].
