The results have been obtained by combining a one-meson-exchange model for the Lambda N -> nN transition in finite nuclei with a Monte Carlo code accounting for the nucleon final state interactions. A weak-decay-model independent analysis of KEK coincidence data allows us to extract Gn/Gp values around 0.3-0.4 for 5_Lambda-He and 12_Lambda-C, thus representing an important progress towards the solution of the Gn/Gp puzzle.
