摘要: Abstract Neutron displacement cross-sections at energies of 15 to 800 MeV have been calculated for the main structural materials. Good agreement between preequilibrium exciton model and intranuclear cascade evaporation calculations has achieved around 20 MeV. A brief description DIDACS computer code developed cross-sections, as well hydrogen helium production in high energy region, is given. Specific features neutron cross-section calculation are discussed.
