Cross sections for the 7Li(n,xn) and 7Li(n,n'γ) reactions between 1 and 20 MeV

Differential cross sections for the production of secondary neutrons and gamma rays from neutron interactions in 7Li have been measured at 500 and 1260 (lab) for incident neutron energies in the range 1 to 20 MeV. An electron linac was used as a white neutron source. Incident neutron energies were determined using time-of-flight techniques for a source-to-sample distance of 48 m. Secondary spectra were determined by analysis of the pulse-height distributions observed in a NE-213 scintillation counter. The results are compared to the current evaluated data file
