摘要
In a kinematically complete experiment on9Be(n, nn)8Begs at 10.3 MeV, the absolute differential cross section of the n-n FSI configuration at Θlab=30° has been measured. It was our particular object to determine the singlet scattering length of the n-n interaction via its final-state interaction being embedded in a multi-nucleon background. An extended and thorough analysis yielded1ann=-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. © 1990 Springer-Verlag.
