Nuclear reaction data support the most essential
part of nuclear technologies (power production, nuclear fuel cycles, environmental monitoring, dosimetry, radiation safety, radioisotope production, radiotherapy, and medical diagnostics, etc.) and sciences(nuclear physics, nuclear chemistry, geophysics, andastrophysics). Nuclear databases are compilations ofmeasured reaction data, and they play a vital rolein providing the best estimate for nuclear reactions
to various science ﬁelds and related areas. One of
the largest and globally used public nuclear reaction
databases is the EXFOR library (EXchange FORmatfor experimental nuclear reaction data).1) The EXFOR
library is a universal common repository for nuclear reactions established in 1967. The International Networkof Nuclear Reaction Data Centres (NRDC) maintains
the EXFOR library under the auspices of the International Atomic Energy Agency (IAEA).2) 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 member of the Asian
countries in 1975. We are responsible for the compilation of the charged-particle- and photon-induced nuclear reactions measured in Japanese facilities.4) Our
contributions to the EXFOR database reaches approximately 10% of the total amount. The database
compilation process involves the scanning of peerreviewed journals for published papers within the EXFOR scope. A unique entry number is assigned to eachselected paper to be compiled for the EXFOR library.
We extract the information of the bibliography, experimental setup, measured physical quantities, measured
numerical data and uncertainties. The information isinput in a single entry of EXFOR. During this process,we contact the corresponding authors for questions on
the contents of the papers and requests for numericaldata.
JCPRG has been cooperating with the RIKEN
Nishina Center for the compilation of data obtainedby RIBF since 2010, which aims to enrich the availability of RIBF data. In 2020, we compiled 45 newarticles produced at Japanese facilities and modiﬁed
18 old entries. This includes 17 articles from RIKEN,
15 new articles, and 2 old entries. The compiled data

are accessible by entry numbers listed in Table 1. We
thank the authors of these papers for their kind cooperation.
We acknowledge that collaboration with RIKEN is agreat help for us to establish an eﬀective procedure forthe compilations. Most RIKEN data are very quickly
compiled after publication and end-users can accessit smoothly. We also thank all authors of RIKEN
articles who kindly provided numerical data. This
greatly helps increase the accuracy and quality of thedatabase.
