Abstract:
Correlated Lambda d pairs emitted after the absorption of negative kaons at rest K-stop(-) A -> Lambda dA' in light nuclei Li-6 and C-12 stop C are studied. A-hyperons and deuterons are found to be preferentially emitted in opposite directions. The Lambda d invariant mass spectrum of Li-6 shows a bump whose mass is3251 +/- 6 MeV/c(2). The bump mass (binding energy), width and yield are reported. The appearance of a bump is discussed in the realm of the [K3N] clustering process in nuclei. The experiment was performed with the FINUDA spectrometer at DA Phi DNE (LNF).
