The ratio of the total exclusive production cross sections for η' and η mesons has been measured in the pp reaction at p beam=3.67 GeV/ c. The observed η ′/ η ratio is (0.83±0.11 +0.23 −0.18)×10 −2 from which the exclusive η ′ meson production cross section is determined to be (1.12±0.15 +0.42 −0.31) μb. Differential cross section distributions have been measured. Their shape is consistent with isotropic η ′ meson production.
