    "abstract": "In this contribution we discuss an evaluation of double-nucleon coincidence\nspectra for the non-mesonic weak decay of Lambda-hypernuclei. The results have\nbeen obtained by combining a one-meson-exchange model for the Lambda N -\u003e nN\ntransition in finite nuclei with a Monte Carlo code accounting for the nucleon\nfinal state interactions. A weak-decay-model independent analysis of KEK\ncoincidence data allows us to extract Gn/Gp values around 0.3-0.4 for\n5_Lambda-He and 12_Lambda-C, thus representing an important progress towards\nthe solution of the Gn/Gp puzzle. Preliminary results for the angular\nasymmetries in the non-mesonic weak decay of polarized hypernuclei are also\npresented.",
