Extension of a nuclear reaction calculation code CCONE toward higher incident energies; Multiple preequilibrium emission, and spectrum in laboratory system

Iwamoto, Osamu  

The CCONE code have been upgraded to improve reliabilities for incident energies higher than 20 MeV. Multiple emission from the pre-equilibrium exciton model was implemented. The effects of change of velocities of composite nucleus in calculation of spectrum in laboratory system were taken into accounts using average velocity approximation. The calculated results were compared with experimental and evaluated data for the nucleon emission spectra for proton and neutron induced reactions for Al. The present results shows reasonably good agreements with experimental data between 20 to 200 MeV. It was found that the present results shows better agreements with experimental data than those of JENDL/HE-2007 especially in low emission energy regions for high incident energy reactions.
