Abstract

Correlated Λd pairs emitted after the absorption of negative kaons at rest K− A → ΛdA′ in light nuclei 6Li and 12C are studied. Λ-hyperons stop and deuterons are found to be preferentially emitted in opposite directions. The Λd invariant mass spectrum of 6Li shows a bump whose mass is 3251 ± 6 MeV/c2. The bump mass (binding energy), width and yield are reported. The appearance of a bump is discussed in the realm of the [K ̄ 3N ] clustering process in nuclei. The experiment was performed with the FINUDA spectrometer at DANE (LNF).
