Abstract

The neutronneutron (nn) quasifree scattering (QFS) at 25.0 MeV and nn final state interaction (FSI) at 17.4 MeV in the nd breakup reaction were studied in this work. First， the absolute breakup cross section was measured with an accuracy of <5 % in the nn QFS. The measured data was analyzed by MonteCarlo simulation based on modern realistic NN potentials (CDBonn， Argonne ??18， Nijm I and II). The measured data exceeds the theoretical prediction based on CDBonn by (16.0±4.6%). Second， the proton emission spectrum around 0° was measured in the nd breakup reaction at 17.4 MeV with kinematical incomplete setup. The data was analyzed by MonteCarlo simulation based on CDBonn. The nn scattering length determined in this work was a nn=（-16.8±0.6） fm.
