论文摘要
报道了中子 - 独立散射横截面的新测量值在中子 - 脱氧于中子中的中子分裂中的中子能量为10.0 meV。对实验设置进行了优化，以评估确定中子中子巧合横截面测量中的中子 - deuteron Breakup中的中子 - 中子合一横截面测量的技术。进行测量的系统不确定性为$ \ pm 5.6 \％$。我们的数据与Faddeev形式主义中使用CD-BONN核子核子电位进行的理论计算一致。 The measured integrated cross section over the quasifree peak is $20.5 \pm 0.5 \text{(stat)} \pm 1.1 \text{(sys)}$ mb/sr$^2$ in comparison with the theory prediction of 20.1 mb/sr$^{2}$.这些结果验证了我们的技术，以确定中子 - deuteron分裂测量中的梁目标光度。
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 $\pm 5.6 \%$. Our data are in agreement with theoretical calculations performed using the CD-Bonn nucleon-nucleon potential in the Faddeev formalism. The measured integrated cross section over the quasifree peak is $20.5 \pm 0.5 \text{(stat)} \pm 1.1 \text{(sys)}$ 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.
