The cross sections of high energy neutron-induced spallation is useful forstudying the transmutation of long-life fission products. However, due to thedifficulty of obtaining high-energy neutrons, the experimental data are stillscarce. The present work studies the possibility to produce high energyneutrons by interactions between deuteron beam and thick target. The Geant4toolkit is applied to simulate the interaction between the deuteron beam andthick target. An analytical method is also developed to calculate the neutronyields emitted in the interaction between the deuteron beam and thick target.The input cross section data is not only taken from the TEDNL-2017 library butalso calculated by the isospin-dependent quantum molecular dynamics model. Itis indicated that it is possible to produce high energy neutron by deuteronbeam interaction with matter. If one wants to get high energy neutrons, low-Zmatter, thin target, and small emission angle may be considered.
