The latest results from the FINUDA experiment on the Non-Mesonic Weak Decay (NMWD) channels of p-shell Λ-hypernuclei are presented and discussed. Spectra of protons from NMWD were obtained for 5 He, 7 Li, 9 Be, 11 B, 12 C, 13 C, 15 N and 16 O. An estimation of the contributions of both Final State Interactions (FSI) and two-nucleon induced (2N) decay processes was performed, following a model independent approach. The previously published results are confirmed by a new analysis of the triple coincidence (π − , p, n) events.

Abstract
The latest results from the FINUDA experiment on the Non-Mesonic Weak Decay (NMWD) channels of p-shell Λ-hypernuclei are presented and discussed. Spectra of protons from NMWD were obtained for 5 He, 7 Li, 9 Be, 11 B, 12 C, 13 C, 15 N and 16 O. An estimation of the contributions of both Final State Interactions (FSI) and two-nucleon induced (2N) decay processes was performed, following a model independent approach. The previously published results are confirmed by a new analysis of the triple coincidence (π − , p, n) events.
