Abstract
The near threshold total cross sections for the pp --> pp eta' and pp --> p pK(+)K(-) reactions has been measured at the COSY-11 facility. Possible pro duction mechanisms are discussed. The energy dependence of the total cross section for the both reactions disagrees with predictions based on the phas e space volume and the proton-proton final state interaction.
