Direct Measurement of Neutron-Neutron Scattering

Published

Conference Paper

© 2003 American Institute of Physics. In order to resolve long-standing discrepancies in indirect measurements of the neutron-neutron scattering length a nn and contribute to solving the problem of the charge symmetry of the nuclear force, the collaboration DIANNA (Direct Investigation of a nn Association) plans to measure the neutron-neutron scattering cross section σ nn . The key issue of our approach is the use of the through-channel in the Russia reactor YAGUAR with a peak neutron flux of 10 18 /cm 2 /s. The proposed experimental setup is described. Results of calculations are presented to connect σ nn with the nn-collision detector count rate and the neutron flux density in the reactor channel. Measurements of the thermal neutron fields inside polyethylene converters show excellent prospects for the realization of the direct nn-experiment.
