Nuclear data, e.g. cross sections, half-lives, anddecay radiation properties, can be obtained throughscientiﬁc investigation of nuclear properties and reactions. The results of experimental measurements ofdiﬀerent nuclear reaction data are distributed in various publications and hence are diﬃcult for users toaccess. Therefore, there is a need to compile the data
into a database. One of the database is the EXFORlibrary, which is maintained by the International Network of Nuclear Reaction Data Centres (NRDC) under the auspices of the International Atomic Energy
Agency (IAEA). As one of the NRDC members, theHokkaido University Nuclear Reaction Data Centre(JCPRG)1) has contributed about 10 percent of thedata on charged-particle nuclear reactions in the EXFOR library.
JCPRG compiles and accumulates charged-particle
data obtained in Japanese facilities in their own
database NRDF. The compiled nuclear reaction data
is available through the online search system of theNRDF and the EXFOR library2) . In addition to thecollaboration with the NRDC network, JCPRG established a collaborative research contract with theRIKEN Nishina Center in 2010, to increase the availability of the nuclear reaction data produced at theRIBF. The compiled ﬁles of the nuclear data produced
at the RIBF are translated to the EXFOR format forthe beneﬁt of nuclear data users. We have addresseda smooth and high-quality compilation of the RIBF
data as one of the important tasks in this collaboration. This write-up provides a brief overview of theJCPRG compilation activity in 2013 regarding experimental nuclear reaction data produced at the RIBF.
Among the papers compiled in 2013, thirteen contained RIBF data in the compilation scope of the EXFOR library, out of which eight papers3–10) publishedin 2013 had already been registered on the EXFORlibrary. Five papers published in 201211–15) had also
been registered on the EXFOR library in 2013. The
data can be easily accessed from the EXFOR searchsystem2) by using the accession numbers given in Table 1. The list of RIBF data compiled into the EXFOR
library is also available on the JCPRG website1) alongwith additional information.
To ensure a high-quality database, we ask authors
to provide the original data plotted in each ﬁgure so

library are accurate. If the original data could not
be obtained from the corresponding author, we digitized numerical data from the plotted ﬁgures using thedigitization software GSYS. If we receive the original
numerical data in the future, we will replace the digitized data with the original data. We also correspondwith the authors about inquiries for data, error, andexperiments as necessary. The numerical data for almost all of the EXFOR entries compiled in 2013 wereproofread by authors, and a detailed description of theentries has been revised according to the authors’ comments.

As a result of the collaboration for four years, mostof the compilation process was well established and isworking well as reported above. We are continuously
making eﬀorts to improve the completeness and usability of the experimental nuclear reaction data produced at the RIBF. For such improvements, the ﬁrst
JCPRG-RNC joint workshop on nuclear data was heldon August 8-9, 201316) . The workshop was helpful
for understanding the present and future status of theRIKEN-JCPRG research collaboration and related nuclear data activities.
