Measurement of the S01 neutron-neutron effective range in neutron-deuteron breakup

Journal Article Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics · December 10, 2022 We report the most precise determination of the S01 neutron-neutron effective range parameter (rnn) from neutron-neutron quasifree scattering in neutron-deuteron breakup. The experiment setup utilized a collimated beam of 15.5 MeV neutrons and an array of ... Full text Cite

Neutron-neutron quasifree scattering in neutron-deuteron breakup at 10 MeV

Journal Article Physical Review C · March 1, 2020 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- ... Full text Cite

Design of an Experiment to Measure ann Using 3 H (γ, pn) n at HIγS

Conference EPJ Web of Conferences · March 25, 2016 We provide an update on the development of an experiment at TUNL for determining the 1S0 neutron-neutron (nn) scattering length (ann) from differential cross-section measurements of three-body photodisintegration of the triton. The experiment will be condu ... Full text Cite
