Abstract

The results of an investigation of the Pontecorvo reaction p̄d → φn with stopped antiprotons in a gaseous deuterium target at NTP are presented. A very selective dedicated trigger was used to collect a sample of about 8.5 × 10⁶ annihilations. It is found that the annihilation rate is Y (p̄d → φn) = (3.56 ± 0.20_-0.1^+0.2) × 10^-6. Comparison with the corresponding value for the ω-meson production demonstrates a large (a factor 40) apparent violation of the OZI rule, even larger than that found in the annihilation on a free nucleon.
