GAMMA-RAY PRODUCTION DATA AND RELATED NUCLEAR STRUCTURE CALCULATIONSComitato Nazionale per l'Energia Nucleare e le Energie Alternative, viale Ercolani 8, I-40138 Bologna, Italy 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.
