DEURACS for deuteron-induced reactions

Deuteron is the first priority for a primary beam in the IMPACT project.

→ Conventional codes (e.g. TALYS, CCONE) are NOT necessarily adequate for

deuteron-induced reactions.

DEURACS was applied to spallation reactions.

Summary and Conclusion

25

Application-oriented nuclear data research that has been conducted in collaboration

between nuclear physics and nuclear engineering communities in Japan

Particularly, the first large-scale collaboration in cross section measurements

The world’s first measurement of cross section data for LLFPs using leading-edge

accelerator facilities (RIKEN/RIBF, J-PARC/MLF, etc.) Application of the inverse

kinematics method in RIBF to nuclear data measurement

Development of the evaluated nuclear data file “JENDL/ImPACT-2018” in close

collaboration between experiments and theory within a short period of time

Contribution to human resource development of young researchers and students

and personal exchange between nuclear physics and engineering communities
