1. Current status of the compilation of nuclear reaction data presented in conference proceedings in JCPRG N.Furutachi, V.Devi, S.Evata, D.Ichinkhorloo, A.Makinaga, M.Odsuren

2. Nuclear reaction database Introduction • The nuclear reaction data is required for the research and development in various fields, such as nuclear physics, astrophysics, nuclear engineering and radiation therapy. • Hokkaido university Nuclear Data Centre (JCPRG) has compiled the nuclear reaction data produced in Japan, and presented the data through • An international nuclear reaction database EXFOR • Japanese database • Nuclear Reaction Data File (NRDF)

3. Nuclear reaction/structure databases • Nuclear reaction database • Unevaluated experimental data • EXFOR • NRDF • Evaluated data • ENDF (Evaluated Nuclear Data File) • JENDL (Japanese evaluated data for neutron-induced reaction) • Structure database • Unevaluated • XUNDL (Experimental Unevaluated Nuclear Data List) • Evaluated • ENSDF (Evaluated Nuclear Structure Data File)

4. EXFOR : The internationalnuclear reaction database • NRDC centres and compilation responsibility • EXFOR is maintained by Nuclear Reaction Dada Centres(NRDC) • NRDC is coordinated byIAEA-NDS • Compilation scope • Neutron data • Charged particle data (CPND) • Photo nuclear data (PhND)

5. JCPRG • Compilation of Japanese nuclear reaction data in JCPRG Basically, the nuclear data is compiled from the peer reviewed journals • Compilation from new papers published every year • 20～30 papers / year • 2～3 papers /month • Compilation from retrospective papers • Year 1950～1980 • Conversion of old NRDF file to EXFOR file

6. EXFOR statics • During the last decade • 20～30 papers /year • ～10 papers from • RIKEN and RCNP

7. Compilation of nuclear data from conference proceedings • Basically, JCPRG does not compile the nuclear data presented in the proceedings without a specific reason, in view of reliability, and difficulty of the management of the preliminary data • However, there are nuclear data which are not published in a regular paper for a long time. The investigation of proceedings is useful to catch the status of such nuclear data. • Sometimes it might be better to consider the compilation of important nuclear data only presented in proceedings.

8. IAEA-NDS search the nuclear reaction data from peer-reviewed journals and conference proceedings, and inform the papers that should be compiled in EXFOR to all centres • Basically, NRDC centres are responsible for scanning of their domestic jounals • Exforcompilation control system • https://www-nds.iaea.org/exfor-master/x4compil/

9. Proceedings scanned by IAEA-NDS • Nuclear Physics, section A (NP/A)－8 • Conference proceedings by American Institute of Physics (AIP)－16 • Journal of Physics, Conference series (JP/CS)－4 • JAEA Conference proceedings－22 • Major international conferences－9 • International conference on Nuclear Data for science and technology (ND) • International Nuclear Physics Conference (INPC) • Symposium on nuclei in the cosmos (NIC) • Total number of conference proceedings that have nuclear reaction data produced at Japan found by IAEA-NDS is ～60 Any kind of action is desired • We investigated the status of the nuclear data given in these proceedings (except for AIP conference proceedings)

10. Whether the nuclear data ofproceedings have been published inpeer-reviewed journalsand already compiled or not was checked • In this process, reactions, physical quantities, beam energies, which are needed to identify the nuclear data are logged for later check of data completeness and duplication • To specify “same experiment” is complicated task

11. 43 proceedings were checked • Data in 19 proceedings have been already compiled from peer-reviewed journals • We can not find data in 24 proceedings in EXFOR • There are old proceedings (oldest: 2006) that have data still not published in peer-reviewed journals

12. One EXFOR file can include multi references, if the nuclear reaction data obtained from “same” experiment. • Example: E2110 (identification number) In this case, there are 3 references • We can add references of conference proceedings to EXFOR entry with peer-reviewed journals • → 19 proceedings are not necessary to compile conference proceedings

13. Discussion • How should we treat proceedings that have data not published in peer-reviewed journals? • There are old proceedings (oldest: 2006). One option is to compile them withdiscussion about reliability with authors. • To specify “same” experiment is complicated task. Close communication with authors reduces this effort. • Especially, data for nuclear engineering distributed in many papers occasionally. Cooperation with authors is essential for management of these data

14. Summary • We have investigated the status of the nuclear data presented in the conference proceedings. • Requirement of IAEA-NDS is cleared to some extent by the present investigation and addition of references of conference proceedings to existing EXFOR files. • Although there are very old proceedings that have data not compiled in EXFOR, careful discussion is necessary for the compilation of these data
