A nuclear database is the compilation of measured
reaction data and plays an essential role in providing
the best estimate for the safety and eﬀective use of nuclear reactions for various purposes. Thus, nuclear reaction databases support the most fundamental aspectof nuclear sciences and technologies, such as nuclear
physics, astrophysics, nuclear reactor development, environmental monitoring, dosimetry, radioisotope production, and radiotherapy.
One of the largest and globally used public nuclear
reaction databases is the EXchange FORmat (EXFOR) library for experimental nuclear reaction data.1)
The EXFOR library is a universal common repository for nuclear reactions. It was established in 1967.
The International Network of Nuclear Reaction Data
Centres (NRDC) maintains the EXFOR library under the supervision of the International Atomic Energy
Agency (IAEA).2) The EXFOR library covers a wide
range of nuclear reactions, such as neutron-, chargedparticle-, and photon-induced reactions.
The Hokkaido University Nuclear Reaction Data
Centre (JCPRG),3) founded in 1973, is responsible forthe compilation of the charged-particle- and photoninduced nuclear reaction experiments conducted inJapanese accelerator facilities.4) Our contributions tothe EXFOR database constitutes approximately 10%of the total amount of the data records. The database
covers papers published in peer-reviewed journals, anda unique EXFOR entry number is assigned to each paper. Each record includes the information of the bibliography, experimental setup, reaction code, measured
numerical data, and uncertainties for the reaction. For
the compilation of each record, we usually request thecorresponding authors to provide us the original data
for the numerical accuracy of the database.
Since 2010, JCPRG and RIKEN Nishina Center
have been cooperating for the compilation of data obtained by RIBF, which aims to enforce the availabilityof RIBF data. In 2021, we compiled 33 new articles
published by Japanese facilities. These include 16 articles from RIKEN, 4 registered articles, and 12 articles
still in the process of registration. The compiled data
are accessible by entry numbers, which are listed inTable 1.
We acknowledge that collaboration with RIKEN is
helpful for us to establish an eﬀective procedure forthe compilations. Most RIKEN data are very quickly
compiled after publication, and end-users can easily

greatly helps increase the accuracy and quality of thedatabase.
