Abstract In a kinematically complete experiment on9Be(n, nn)8Begs at 10.3 MeV, the absolute differential cross section of then-n FSI configuration at Θlab=30° has been measured. It was our particular object to determine the singlet scattering length of then-n interaction via its final-state interaction being embedded in a multi-nucleon background. An extended and thorough analysis yielded1 a nn =−16.5±1.0 fm which is consistent with the results of the most recent and most precise kinematically complete measurements with three hadrons in the final state. These, however, altogether contradict the values deduced from π− d→nnγ.
