Progress in Developing Nuclear Reaction Calculation Code CCONE for High Energy Nuclear Data Evaluation

To adapt the CCONE code to the high energy nuclear data evaluation, the preequilibrium exciton model part of the code has been extended to multiple particle emission. This is realized by sequential calculation of the decay of exciton states for all residual nuclei left by particle emissions. In addition, Iwamoto-Harada cluster coalescence model has been incorporated in the multiple-emission exciton model to improve the accuracy of calculated cluster emission spectra for deuteron, triton, 3He and α particles. The calculated light particle emission spectra are compared with experimental and evaluated data.
