A study of recent improvements in spallation reaction models
S. E. Taylor
New developments in the combined Liege intra-nuclear cascade and ABLA evaporation model for studying spallation reactions have been investigated. Predictions of proton, neutron and Helium-4 cross-sections have been made for nucleons incident on a variety of targets at a range of incident energies, and these have been compared to those obtained using previous versions of the model. The recent modifications are found to have had a beneficial effect on the predictions of the model for the most part, particularly for Helium-4 cross-sections, which were previously only accommodated in the evaporation part of the model. However, in some cases the modifications seem to have had a detrimental effect on predictions of some observables, particularly for neutron double-differential cross sections on lead at low incident energies. Taken as a whole, the results are encouraging, but also indicative of some small flaws that future improvements will need to address.
