  The ratio of the total exclusive production cross sections for $\eta\prime$
and $\eta$ mesons has been measured in the $pp$ reaction at $p_{beam}=3.67$
GeV/c. The observed $\eta\prime/\eta$ ratio is
$(0.83\pm{0.11}^{+0.23}_{-0.18})\times 10^{-2}$ from which the exclusive
$\eta\prime$ meson production cross section is determined to be
$(1.12\pm{0.15}^{+0.42}_{-0.31})\mu b$. Differential cross section
distributions have been measured. Their shape is consistent with isotropic
$\eta\prime$ meson production.
