摘要：

The near threshold behaviour of the reaction cross section for pp --> pp eta', recently measured in experiments at COSY and SATURNE, is analyzed. The interaction in the pp as well as in the eta'p final states is taken into account. The suppression of the total cross section for this process at excess energies Q < 3 MeV observed in these experiments is interpreted as an evidence for a strong repulsive eta'p interaction.
