Measurement of cross sections for the 27Al(n,n'γ)27Al reaction near threshold
Description
Cross-section ratios for production of 0.843-, 1.013-, and 2.209-MeV gamma rays at 550 by the 27Al(n,n'γ)27Al reaction relative to fast-neutron fission of 235U have been measured at intervals of approx. 0.05 MeV from threshold up to approx. 2.5 MeV, with an average neutron energy resolution of approx. 0.08 MeV. These ratios and ENDF/B-IV fission cross sections were used to compute gamma-ray production cross sections. Gamma-ray angular distributions were measured at E/sub n/ = 1.112, 1.310, 1.512, 1.714, 1.914, 2.118, 2.310, and 2.512 MeV. These distributions were found to be isotropic within the experimental errors. The experimental results are compared with data from the literature and with results from optical/statistical model calculations of neutron inelastic scattering from aluminum
