Comparison of eta and eta ' production in the pp -> pp eta(eta ') reactions near threshold

• The total cross section of the pp --> pp eta' reaction has been measured at two energies near threshold by detecting the final protons in a magnetic spectrometer. The values obtained are about a factor of 70 less than for the corresponding eta production,
