HELIUM PRODUCTION CROSS-SECTIONS IN STRUCTURAL-MATERIALS IRRADIATED BY PROTONS AND NEUTRONS AT ENERGIES UP TO 800 MEV

The proton and neutron helium production cross sections have been obtained for a number of structural materials in the energy range between 10 and 800 MeV. The cross-section calculations have been carried out using the DIDACS/90 code package and the ALICE/ASH code. Some features of high energy helium production cross-section calculations are discussed.
