    The reactions of 24.6-GeV/c- and Ξ- incident on a scintillator target were studied in a counter-spark chamber experiment. Upper limits on the production cross sections of*- resonances which decay into Λ0π- and Ξ*- resonances which decay into Λ0K- were obtained. A single Ω- that was produced in the scintillator target has been observed, corresponding to a 115-μb/nucleon production cross section if produced by a Ξ-. The Λ0π- mass spectrum was found to be consistent with a Deck-type threshold enhancement.
