Abstract

A direct experimental evidence of the occurrence of the weak reaction Λnp→ nnp in nuclei has been obtained by the FINUDA experiment. Three events have been found that can be attributed to ⁷_ΛLi and ⁹_ΛBe two nucleon-induced non mesonic weak decays. The kinematic analysis of such events is presented here.
