  The reaction $ pp\to pp\bf \omega$ was investigated with the TOF
spectrometer, which is an external experiment at the accelerator COSY
(Forschungszentrum J\"ulich, Germany). Total as well as differential cross
sections were determined at an excess energy of $93 MeV$ ($p_{beam}=2950
MeV/c$). Using the total cross section of $(9.0\pm 0.7 \pm1.1) \mu b$ for the
reaction $ pp\to pp\omega$ determined here and existing data for the reaction
$pp\to pp\bf \phi$, the ratio
$\mathcal{R}_{\phi/\omega}=\sigma_\phi/\sigma_\omega$ turns out to be
significantly larger than expected by the Okubo-Zweig-Iizuka (OZI) rule. The
uncertainty of this ratio is considerably smaller than in previous
determinations. The differential distributions show that the $\omega$
production is still dominated by S-wave production at this excess energy,
however higher partial waves clearly contribute. A comparison of the measured
angular distributions for $\omega$ production to published distributions for
$\phi$ production at $83 MeV$ shows that the data are consistent with an
identical production mechanism for both vector mesons.
