Abstract
A study has been performed of the reaction using in-flight antiprotons from 1.1 to 2.0 GeV/c incident momentum interacting with a hydrogen jet target. The reaction is dominated by the production of a pair of φ mesons. The cross section rises sharply above threshold and then falls continuously as a function of increasing antiproton momentum. The overall magnitude of the cross section exceeds expectations from a simple application of the Okubo-Zweig-Iizuka rule by two orders of magnitude. In a fine scan around the resonance, no structure is observed. A limit is set for the double branching ratio for a spin 2 resonance of and
