Cross sections for the Al(n,xn) and Al(n,x$gamma$) reaction between 1 and 20 MeV

Differential cross sections for the production of secondary neutrons and photons from aluminum have been measured at 127$sup 0$ (lab) for incident neutron energies in the range 1 to 20 MeV. An electron linac was used as a neutron source with a white spectrum. Incident neutron energies were determined using time-of-flight techniques for a source-to-sample distance of 48 m. Secondary spectra were determined by unfolding the pulse-height distributions observed in a NE-213 scintillation counter. The results are compared to the current evaluated data file (ENDF/B-IV, MAT 1193). (auth
