摘要：
New measurements of the neutron-neutron quasifree scattering cross section in neutron-deuteron breakup at an incident neutron energy of 10.0 MeV are reported. The experiment setup was optimized to evaluate the technique for determining the integrated beam-target luminosity in neutron-neutron coincidence cross-section measurements in neutron-deuteron breakup. The measurements were carried out with a systematic uncertainty of +/- 5.6%. Our data are in agreement with theoretical calculations performed using the CD-Bonn nucleonnucleon potential in the Faddeev formalism. The measured integrated cross section over the quasifree peak is 20.5 +/- 0.5(stat) +/- 1.1(sys) mb/sr(2) in comparison with the theory prediction of 20.1 mb/sr(2). These results validate our technique for determining the beam-target luminosity in neutron-deuteron breakup measurements.
