In this report, we present our recent activities of the compilation of experimental
nuclear reaction data. In the ﬁscal year from April 2018 to March 2019, we compiled
78 new entries and transmitted 13 TRANS ﬁles.

1Introduction

Nuclear reaction data are used in various ﬁelds, such as nuclear physics, engineering andmedicine. The data can be accessed to a nuclear database through the Internet. The databaseis constructed in a special format called EXFOR (EXchange FORmat for experimental nuclear
reaction data) [1]. The format is designed to accommodate experimental data with corresponding
bibliographies and experimental descriptions including error analysis for proper interpretationof the stored experimental data.
EXFOR is maintained by the International Network of Nuclear Reaction Data Centres (NRDC)
coordinated by the International Atomic Energy Agency (IAEA) [2]. The NRDC collaborates
in the compilation of experimental data and development of related software for compilationand dissemination. The Hokkaido University Nuclear Reaction Data Centre (JCPRG) [3] isa member of NRDC and has contributed about 10% of the charged-particle nuclear reaction
data in the EXFOR library. JCPRG provides the compiled nuclear reaction data in both theinternational (EXFOR) and domestic (NRDF) [4] formats through an online search system.
In this report, we presented our compilation activities of the ﬁscal year from April 2018 toMarch 2019.

2Activity progress

The main task of the JCPRG is to compile charged-particle induced reaction data obtainedin Japanese facilities. The following steps are carried out to achieve the task.
• Survey of papers to be compiled from scientiﬁc journals• Compilation of papers in EXFOR format• Transmission of TRANS ﬁles (sets of compiled entries) to IAEA- 13 -

Journal Survey

Under collaboration with the NRDC network, experimental data published in scientiﬁc journals are continuously surveyed. Sometimes we ﬁnd some published papers that are not in thescope of EXFOR but are as of NRDF. The lists of the surveyed journals are as follows:• Physical Review C (PRC)• Physical Review Letters (PRL)• Nuclear Physics A (NP/A)• Physics Letters B (PL/B)• The European Physical Journal A (EPJ/A)• Journal of Nuclear Science and Technology (NST)• Journal of Physics G (JP/G)• Nuclear Instruments and Methods in Physics Research A (NIM/A)• Nuclear Instruments and Methods in Physics Research B (NIM/B)• Progress of Theoretical Physics (PTP)• Journal of Physical Society of Japan (JPJ)• Nuclear Science and Engineering (NSE)

Compilation

In the ﬁscal year 2018, we compiled 78 new papers and revised 40 entries reporting on nuclear
reaction experimental data obtained in Japan. Each new paper is assigned to a compiler. The
compiled entries are peer-reviewed by other compilers. For a higher quality of contents and theaccuracy of data in the NRDF and the EXFOR library, we contact authors to obtain original
numerical data plotted in each ﬁgure. In case that the original data cannot be obtained from thecorresponding author, we digitize numerical data from the plotted ﬁgures with the digitization
software GSYS [5].
We have also cooperated with the RIKEN Nishina Center for compilation since 2010. The
purpose of the cooperation is to increase the availability of the nuclear reaction data produced
at the RIBF. The compiled ﬁles of nuclear data produced at the RIBF are translated into theEXFOR format for the beneﬁt of nuclear data users. In the ﬁscal year 2018, ? papers including
the RIBF data were compiled. Therefore, most of the recent experimental nuclear reaction datafrom the RIBF have successfully been compiled in the EXFOR database.

Transmitted File in 2018

The most important work is to open EXFOR entries including the experimental nuclear reaction data worldwide. Our compiled entries are transmitted to the NRDC to upload into theirservers to public. The transmission includes the new compiled entries as well as the modiﬁedentries. In 2018, 13 TRANS ﬁles: E112, E113, E114, E115, E116, E117, E118 ,E119, E120,E121, E122, K018 and R029 are submitted to the IAEA. Table 1 represents the TRANS ﬁlesthat include the new as well as modiﬁed entries with their accession number. These 13 TRANS
ﬁles contain 78 EXFOR new entries and 40 modiﬁed entries.

3Summary

We have established an eﬀective procedure to compile all of the new publication reporting
experiments performed in Japan. We reported recent compilation work in the JCPRG in thisarticle and summarized the status of the EXFOR ﬁle transmission: the 13 TRANS ﬁles, named
as E112, E113, E114, E115, E116, E117, E118 ,E119, E120, E121, E122, K018 and R029 weretransmitted in ﬁscal year 2018.
