Résumé : Decay branching ratios of the {Mathematical expression}c hypernucleus have been measured using a sample of hypernuclei produced in the interactions at rest of K--mesons in a helium bubble chamber. The observation of 6 π+-mesonic decays leads to a value of 0.043±0.017 for the π+-mesonic/π--mesonic decay branching ratio. No examples of the charged two-body nonmesonic decays of the hypernucleus were observed. © 1976 Società Italiana di Fisica.
