Abstract

Results are presented from a search for the production of narrow $\overline{p}p$ states in antiproton interactions at 8.3 and 13.0 GeV/c. Cross-section upper limits have been established for four candidate baryonium states. The upper limits (95% probability level) range from 0.21 to 1.29 \ensuremath{\mu}b for inclusive forward production, and from 0.11 to 0.89 \ensuremath{\mu}b for backward production in the final state ${\ensuremath{\omega}}_{f}^{0}(\overline{p}p)$.
