Abstract

The regions of neutron-proton and neutron-neutron quasifree scattering (QFS) have been investigated in the n-d breakup reaction at 26 MeV, measuring absolute cross sections with an accuracy of a few percent. The data were analyzed by means of detailed Monte Carlo simulations based on rigorous three-body calculations with realistic nucleon-nucleon potentials. For n-p QFS, good agreement between theory and experiment was found. In contrast, for n-n QFS the experimentally determined cross section is almost 20% larger than the theoretical predictions.
