Systematic Evaluation of Neutron-Emission Cross Section for the Reactions Induced by Protons of 80–800 MeV

Abstract

A moving source model uses a relatively small number of parameters. The neutron data for the spallation reactions induced by protons of 600 to 800 MeV are well reproduced by the moving source model. At incident energies below 400 MeV, however, the use of this model leads to an unsuccessful result. A new idea of a double moving source model is introduced in the lower energy region. The combination of the two models enables us to parameterize the double differential cross sections of neutron emission for incident protons of 80 to 800 MeV.
