Compilation of nuclear reaction data from the RIBF in 2015
D. Ichinkhorloo,∗1 M. Aikawa,∗1,∗2 S. Ebata,∗1 S. Imai,∗3 N. Otuka,∗2,∗4 A. Sarsembayeva,∗1 and B. Zhou∗1Nuclear data such as the data of cross sections, radiations emitted from radioactive isotopes, level properties of isotopes are used widely in many fields. Nuclear
data play a key role in understanding the nature ofnuclear structures and nuclear reactions. On the otherhand, as the fundamental input to various codes fornuclear applications, they are also very important inmedical radiotherapy, shielding and radiation protection, and some related engineering works. Therefore,
it is of great significance to build a nuclear databasefor providing nuclear data service in various fields.
EXFOR1) is the name of the data library containing
experimental nuclear reaction data. The EXFOR library contains numerical data, bibliographic information, and experimental information including sourcesof uncertainties. On the contrary, such data and information can be retrieved from the database by nuclear
data users. Additional information, such as experimental setups, is also available.
Experimental data are found in the EXFOR
database, which is maintained by the International
Atomic Energy Agency (IAEA)2) and the International
Network of Nuclear Reaction Data Centres (NRDC).
The NRDC collaborates for database compilation andrelated software development. One of the NRDC members is the Hokkaido University Nuclear Reaction Data
Centre (JCPRG)3) . JCPRG has contributed to about
10 percent of the data on charged-particle nuclear reactions in the EXFOR library. In the JCPRG, compilednuclear reaction data in the NRDF (Nulear Reaction
Data File) and EXFOR formats are available throughthe online search system of the NRDF and EXFOR
libraries1) , respectively.
Under collaboration with the NRDC network, experimental data published in scientific journals are continuously surveyed. Among the data obtained, thecharged-particle and photon induced data obtained
from the facilities in Japan should be compiled byJCPRG. The compiled files of nuclear data produced
at the RIBF are translated into the EXFOR format
for the benefit of nuclear data users. In this article, wereport on our activities in 2015, especially the compilation of experimental nuclear reaction data from theRIBF.
In 2015, we compiled 29 new papers reporting onexperiments performed in Japan. Among them, 11 papers were from the RIBF data and satisfied the compilation scope of the EXFOR library. All data are

accessible by the entry numbers listed in Table 1. For
higher quality of contents, the corresponding authors
were requested to provide numerical data of the compiled papers. Most of the compiled RIBF data in 2015
are provided by the authors. Such additional information is also available with a list of compiled RIBF dataon the JCPRG website.

We established an effective procedure to compile allof the new publications during the last five-year collaboration with the RIKEN Nishina Center. Therefore, most of recent experimental nuclear reaction datafrom the RIBF have successfully been compiled in theEXFOR library. It is recommended that such collaboration should be further developed for experiments
at the RIBF. By using these compilations, experiment
data from the RIBF can also be served in a more convenient and fast manner for nuclear research and studies
in other fields.
