Abstract： We investigate the 800MeV proton-induced spallation reactions on various targets by the improved quantum molecular dynamics (ImQMD05) model incorporated with a statistical decay model (SDM). The influence of the nucleon--nucleon effective interaction on proton induced spallation reactions is studied by using different Skyrme interactions. It is found that the low energy part of the neutron double differential cross sections (DDCS), which is mainly contributed from the decay of the excited residue, is influenced by the effective nucleon--nucleon interaction strongly, while the high energy part of neutron DDCS is influenced weakly. Among the Skyrme interactions used in the calculations, the calculation results with SkP give the best agreement with the experimental data.
