Abstract: We investigate the K- He-3 and K+K- interactions in the reaction pd -> He-3 K+K- near threshold and compare our model calculations with data from the MOMO experiment at COSY-Julich. A large attractive effective K(-)p amplitude would give a significant K- He-3 final-state interaction effect, which is not supported by the experimental data. We also estimate upper limits for the a(0)(980) and f(0)(980) contributions to the produced K+K- pairs.
