Summary
We wish to report the existence of a narrow resonance in the ( ) system which we observed in the study of the interactions of negative K mesons in the LRL 72-in. hydrogen bubble chamber. The separated incident K beam, originating in the Bevatron, had a momentum of 1.80 0.08 GeV/c; the uncertainty includes both the 6% momentum spread of the beam and the momentum loss in the chamber. The film was scanned for events with the following topology: "one positive secondary, one negative secondary with a decay, and one or two associated V's.'' (Extracted from the introductory part of the paper.).
