The GEM Code - the Generalized Evaporation Model and the Fission Model
We have developed the GEM code based on the generalized evaporation model proposed by Furihata and the RAL fission model. The parameters for the fission model, which determine the mass, charge, and kinetic energy distributions of fission fragments are reevaluated in this study. The cross sections for nuclide produced from protons incident on 208Pb and 198Au are estimated by using a combination of the intranuclear cascade model (INC) implemented in the LAHET code and the GEM code. INC/GEM reproduces successfully the cross sections for fission fragment production as well as light particle productions.
