Calculations of photon production cross sections and spectra, arising from neutron capture and inelastic scattering reactions, are performed for some structural materials in the incident neutron energy range 1.0 MeV < En < 20 MeV, of interest for applied purposes. The role played by nuclear structure effects is investigated as far as both discrete and continuum levels and relevant electro-magnetic transitions are concerned. Properties of the giant dipole resonance are discussed as regards the validity of Brink-Axel hypothesis.
KEYWORDS: neutron induced reactions, photon production cross sections and spectra, nuclear level density, giant dipole resonance, interacting boson model
