Abstract : Interaction of neutrons with silicon have been studied by measuring gamma-ray-production cross sections. For incident mean neutron energies E(n) = 5.35, 5.85, 6.4, 6.9, 7.45, 7.95, 8.5, and 9.0 MeV spectra were obtained for a natural silicon sample. Data were also obtained at E(n) = 5.9 MeV, gamma ray scattering angle = 55 degrees for a sample of 29SiO2 enriched to 95% in 29Si, and for a similarly enriched sample of 30SiO2. These data have been studied to obtain absolute cross sections for production of gamma rays for the incident neutron energies quoted above. The spectra were studied for gamma rays which could be associated with deexcitation of nuclear levels having unknown decay modes. (Author)
