Abstract
Based on realistic calculations for the nonmesonic(-)decay rate of (3)Lambd a H we demonstrate that, in principle, it is not possible to measure the to tal n- and p-induced decay rates and as a consequence Gamma(n)/Gamma(p) for that lightest hypernucleus. The calculations are performed with modern YN fords based on various meson exchanges and taking the final state interacti on among the three nucleons fully into account. Our findings might have con sequences also for the interpretation of experimental Gamma(n)/Gamma(p) rat ios for heavier hypernuclei where severe discrepancies exist to theoretical Gamma(n)/Gamma(p) ratios.
