Outline of Final Research Achievements

The outcome of this research is featured by 3 parts. The first one is the measurement of fission fragments and secondary neutrons from a compound nucleus formed by nucleon-transfer reactions of Pb-208 and O-16.The second one is the improvement and application of fission reaction model FIFRELIN authored by CEA in France to get insight into the background physics of fission and its verification. As the last thing, GEM and EBITEM, the evaporation models developed by JAEA, were improved so as to complement fission and cover whole processes of statistical decay. New models and databases were incorporated to take into account for phenomena which were not considered in the previous versions.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は、原子核の分裂や蒸発といった原子力施設・放射線施設において基本的な核反応を正確に、かつ多様な側面を予測できるようにしたもので、既にその成果は論文として公開されただけでなく、世界に8000人以上のユーザーを持つ放射線輸送計算コードPHITSに実装され配布されているため、ユーザーによるモデルの使用によって、本研究成果は社会で活用されている。
また、本研究で得られた基礎的知見についても今後開発されるPHITSのモデルに反映する予定であり、今後長期的にも恩恵を期待できる。
