Neutron-neutron quasifree scattering in neutron-deuteron breakup at 10 MeV
Abstract
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 nucleon-nucleon potential in the Faddeev formalism. The measured integrated cross section over the quasifree peak is 20.5 ±0.5 (stat)±1.1 (sys)mb/sr2 in comparison with the theory prediction of 20.1 mb /sr2 . These results validate our technique for determining the beam-target luminosity in neutron-deuteron breakup measurements.
