Nuclear-reaction data support the most essential
part of nuclear technologies (e.g., nuclear power production, nuclear fuel cycles, environmental monitoring,
dosimetry, radiation safety, radioisotope production,
radiotherapy, and medical diagnostics) and sciences(e.g., nuclear physics, nuclear chemistry, geophysics,and astrophysics). Nuclear databases play a vital rolein providing the best estimate for nuclear reactions toa wide range of data users in various scientiﬁc ﬁelds
and related areas. One of the largest global nuclear
reaction databases open to the public is the EXFOR
library (EXchange FORmat for experimental nuclear
reaction data).1) The EXFOR library is a universal
common repository for nuclear reactions establishedin 1967. The International Network of Nuclear Reaction Data Centres (NRDC) maintains the EXFOR
library under the auspices of the International Atomic
Energy Agency (IAEA).2) The scope of the EXFOR
library covers a wide range of nuclear reactions suchas neutron-, charged-particle-, and photon-induced reactions.
Our group, the Hokkaido University Nuclear Reaction Data Centre (JCPRG),3) was founded in 1973 andjoined the NRDC as the ﬁrst Asian member in 1975.
We are responsible for the compilation of chargedparticle-, and photon-induced nuclear reactions measured at facilities in Japan.4) Our contributions to theEXFOR database account for ∼10% of the complete
database. The database compilation process involves
the scanning of peer-reviewed journals for publishedpapers within the EXFOR scope. A unique entry number is given to each selected paper to be compiled for
the EXFOR library. We extract information from thebibliography, experimental setup, measured physicalquantities, measured numerical data, and uncertainties. The information is input in a single entry ofEXFOR. During this process, we contact the corresponding authors with questions on the contents of thepapers and requests for numerical data.
JCPRG has been cooperating with the RIKEN
Nishina Center since 2010 for the compilation of dataobtained by RIBF, which aims at the enhancement ofthe availability of the RIBF data. Our activities related to the RIBF experiments are as follows. We
have compiled 48 new articles produced at Japanesefacilities and modiﬁed 42 old entries. This includes 10

articles from RIKEN, 6 new articles, and 4 old entries.
The compiled data are accessible by the entry numbers
listed in Table 1. The status of those compilations isperiodically reported via Nishina Center News.
We acknowledge that collaboration with RIKEN isa great help for us to establish an eﬀective procedure
for the compilations. Most of the RIKEN data arevery quickly compiled after publication, and the end
users can access them smoothly. We also thank all theauthors of the RIKEN articles who kindly provided numerical data. This greatly helps increase the accuracy
and quality of the database.
