Neutron cross section measurements at IRMM

摘要

The Neutron Physics Unit of IRMM performs a broad spectrum of neutron measurements. Cross section measurements and parameter determinations for neutron-induced reactions may be performed by time-of-flight measurements at the high-resolution white neutron source Gelina and at single energies at the Van de Graaff laboratory. At Gelina, neutrons with energies from thermal to several hundred keV are routinely employed for transmission, capture, fission and charged particle emission measurements. Several examples will be shown. Here it will also be shown how the energy range up to 18 MeV may be used for inelastic scattering cross section measurements. For the Van de Graaff laboratory measurements of cross sections with the activation technique will be highlighted, as well as work on the ~(10)B(n,α) reaction. Indications will be given of the developments for the near future.
