Abstract

Novel data from the K-stopA absorption reaction in light nuclei6,7Li and9Be are presented. The study aimed at finding Λt correlations. Regardless of A, the Λt pairs are preferentially emitted in opposite directions. Reaction modeling predominantly assigns to the K-stopA → Λt(N)A' direct reactions the emission of the Λt pairs whose yield is found to range from 10-3to 10-4/K-stop. The experiment was performed with the FINUDA spectrometer at DAΦNE (LNF).
