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.
