Neutron yields from proton-induced spallation reactions in thick targets of lead

“…Details of the nuclear model and the associated pammeters used in the LAHET/HETC version of the INCE model are discussed in several publications . [4][5][6][7][8][9][10][11][12][13][14] For projectile energies above 100 MeV, a comparison15 of the INCE model predictions of the differential neutron yield with measured data shows that the model predicts relatively comect neutron production in the evaporation region, but underpredicts neutrons of energy above 50 MeV, especially at large scattering angles. At lower projectile energies discrepancies are progressively larger, as exemplified by the comparison of neutron spectra] 6 from 208Pb (p,xu) reactions at 15 MeV proton energy.…”
