The ratio of the total exclusive production cross sections for eta' and eta
mesons has been measured in the pp reaction at p(beam) = 3.67 GeV/c. The o
bserved eta'/eta ratio is (0.83 +/- 0.11(-0.18)(+0.23)) x 10(-2) from which
the exclusive eta' meson production cross section is determined to be (1.1
2 +/- 0.15(-0.31)(+0.42)) mub Differential cross section distributions have
been measured. Their shape is consistent with isotropic eta' meson product
ion. (C) 2000 Elsevier Science B.V. All rights reserved.
