Based on realistic calculations for the nonmesonic decay rate of Λ3H we demonstrate that, in principle, it is not possible to measure the total n- and p-induced decay rates and as a consequence Γn/Γp for that lightest hypernucleus. The calculations are performed with modern YN forces based on various meson exchanges and taking the final state interaction among the three nucleons fully into account. Our findings might have consequences also for the interpretation of experimental Γn/Γp ratios for heavier hypernuclei where severe discrepancies exist to theoretical Γn/Γp ratios.
