N. Takibayev and V. Kurmangalieva(al-Farabi Kazakh National University, the Republic of Kazakhstan)First of all, we, the representatives of Kazakhstan and the staff of CA-NRDB, would like tocongratulate the Hokkaido University database for its 40th anniversary! Organizing and leading roleof the Hokkaido University database in the development of the database network of Asian countries
is highly appreciated and recognized by many international organizations.
Our database CA-NRDB recently joined the Asian community of databases on nuclear reactions.
The intention to create a nuclear reactions database in Kazakhstan was announced by us at theinternational meeting of representatives of the databases in Asia, which took place in the autumn of2011 at the Hokkaido University, Sapporo, Japan. In Kazakhstan, the Chair of Theoretical andNuclear Physics at al-Farabi Kazakh National University initiated the organization of this Database.
The idea was supported by all the institutions, organizations and leading scientists in Kazakhstan
and Central Asian countries which work in the fields of nuclear physics, nuclear energy andradiation ecology. Many leading scientists have expressed their desire to cooperate. The Database
therefore got its status and its name as the Central Asian nuclear reactions database (CA-NRDB).
We then began our work organizing the Database, coordinating our its activities with theCommittee on Atomic Energy of Kazakhstan, the Ministry of Education and Sciences, the National
Nuclear Center of Kazakhstan. A small working group was formed at the Kazakh National
University consisting mainly of young physicists (undergraduate and graduate). Leading nuclear
scientists from Kazakhstan were invited to advise the Database (Professors N. Burtebaev and N.
Takibaev) and from other countries: Professors K. Kato, M. Aikawa, N. Otsuka, V. Varlamov and R.
Yarmuhammedov.
It was a challenging task for us here since we had no previous experience in this area, no
specialized facilities or equipment. It was therefore decided to take part in the funding competitionof research projects announced by the Ministry of Education and Science (MES) for 2013-2015.
According to the MES requirements, there had to be an educational part in the proposed project,
and the database itself was to be in three languages: Kazakh, Russian and English. For us it was
important to make all sections suitable for use by junior scientists and attractive in terms ofcomputer design and aesthetics. As a model, we used educational database of the Moscow State
University (MSU). Note that the MSU database had been in operation for several decades and had
extensive experience providing services to specialists and students. For the small group of four
students of our university and thee part-time consultants, this scope of work is quite excessive. But
we are doing our best!
We developed own database structure and did computer designing. Specialized search andcalculation programs were designed and adapted, reference and training materials on theoretical andexperimental nuclear physics and related disciplines have been identified, adjusted for our needs. In
many cases, we developed the content for the library sections and created electronic versions ofpreviously published books and articles. Our team managed to organize a search for rare works
published by scientists of Kazakhstan and Central Asia in the past and to include these materials in
the Database.
215

The own website has been designed, and vast data have been collected and processed.
Particularly for the educational part of the resource, we organized publishing of own preprints. A
pilot version of the CA-NRDB has been launched at the University’s web portal, and the structure
and main components have been shaped.
One of the important tasks performed by the project was to develop and strengthen international
scientific ties, cooperation with the IAEA and the international network of databases. Our contacts
and collaborations with scientists from Hokkaido University and nuclear databases specialists wereand remain among the priorities of our international scientific cooperation. Recommended by thecolleagues in Hokkaido University, our young CA-NRDB was accepted into the international
network of databases supervised by the IAEA. Now our junior specialists can participate in thework of the IAEA technical meetings on nuclear data and acquire useful professional experience.
The project team takes part in activities of the international nuclear database network under
IAEA. The compiled papers and works undergo multilevel expert assessment before inclusion into
the Database. IAEA performed and approved for incorporation to EXFOR about two dozens ofpapers by scientists from Kazakhstan and Uzbekistan; there were reviewed and prepared forcompilation about a dozen more papers by Kazakhstani scientists published in soviet period.
We would like to acknowledge Professor Kato for his care and advice. His support was crucial inreaching cooperative agreements between al-Farabi University and Hokkaido University, as well aswith the University of Osaka, and with IAEA. Our university has got a bilateral agreement with theJapan Atomic Energy Agency, which allows us to run exchange of experts and training of our juniorscientists in Japan research centers in Tsukuba.
Through all the stages of the Database development, a lot of support was provided by Prof. K.
Kato and his research team in Hokkaido University. Our joint work is developing in the following
directions: training of personnel and junior scientists, joint research in theoretical nuclear physics,
new international cooperation projects, organization of international conferences and workshops.
We would also like to mention support from Dr. N. Otsuka in linking our CA-NRDB to the
IAEA.

Nuclear Reaction data have been a crucial resource in nuclear technology (e.g. fission fusionenergy and medical diagnostics) as well as science (e.g., nuclear physics, astrophysics, nuclear
chemistry and earth science). Generation and proper use of nuclear data comprising measurement
and evaluation of recommended values of accurate nuclear data belong to the cutting-edge scienceand form an important component of basic nuclear physics. Various reaction models have beendeveloped based on nuclear theory and phenomenology and they have been verified byexperimental nuclear reaction data and utilized for revision of evaluated nuclear reaction data. The
International network of Nuclear Reaction Data Centre (NRDC) was established under the auspicesof the International Atomic Energy Agency (IAEA) to coordinate the worldwide collection,compilation and dissemination of nuclear reaction data in EXFOR database. International network
established in 1969 with four nuclear data centre: BNL/NNDC, OECD/NEA data bank, IAEA/NDS,
CJD/IPPE. The collection, compilations and dissemination of experimental nuclear reaction data
have expanded ever since the network was founded and at present the NRDC consist of 14 nuclear
data centres. Historically, thus far, the Indian nuclear reactor design communities have been using
nuclear physics data evaluated by foreign sources available freely from the IAEA.
Hokkaido University Nuclear Data Centre (JCPRG) compiles and accumulates charged-particle
nuclear reaction data obtained in Japanese facilities in their own data format (NRDF: Nuclear
Reaction Data File) which are distributed online. A part of compiled files is translated to the
EXFOR format for the transmission of the experimental nuclear data between national andinternational nuclear data centers for the benefits of nuclear data users in all countries. Nuclear dataphysics centre of India (NDPCI) being formed within DAE-BRNS as a project has endorsed therecommendations of the NRDC (IAEA-NRDC-2008) and since from the development there is an
important contribution of both the countries to the Asian nuclear data centre. JCPRG has
collaborated also with other Asian research centres. JCPRG makes important contributions in the
nuclear reaction data activity by making collaboration with Asian countries. JCPRG always tried todevelopment of Asian nuclear collaboration. Asian nuclear reaction database development
workshops were held every year in different Asian countries, (Japan (2010), China (2011), Korea(2012), Kazakhstan (2013) and India (2014). Participant from different Asian countries like Japan,
China, Korea, Kazakhstan, Vietnam, Pakistan, IAEA, Vienna and India participated in theseworkshops. In 2014, M. Aikawa from Hokkaido University visited India to attend the 5th Asian
nuclear reaction database development workshop and discussed about the compilation status in
Hokkaido University. Vidya Devi also presented about the workings and presented various
functions of the GSYS 2.4.3 and Japanese editor HENDEL.
In 2011, Vidya Devi from India joined postdoc fellowship at Meme Media Laboratory, Hokkaido
University under the supervision of Professor K. Kato and Professor M. Aikawa. She was devoted
to compilation of nuclear data under the collaboration between Meme media laboratory and nuclear
217

reaction data centre (JCPRG), Hokkaido University. During this period she also participated in thecoordination of articles, journal surveys and checking of compiled entries, learnt Compilation
Japanese software HENDEL and digitization with the help of GSYS 2.4.3. In 2013 she delivered atalk on the GSYS 2.4.3 in EXFOR workshop was held in Banaras Hindu University India.
During this period she also participated in the other activities of theoretical nuclear laboratory,
she studied the structure of nuclei lying in A=120-200 mass region with the help of models likeAnharmonic Rotor Model (ARM), Rotation Vibration Model (RVM) and Interacting Boson model(IBM). We study the nuclear structure of transitional nuclei, softness in deformed nuclear structure,
variation of rotational energy with the asymmetric parameter and deformation parameter, newenergy levels of nuclei of A=120-200 mass region. By using Interacting Boson Model we calculate
the new energy levels, Quadrupole Moment, B(E2) values and B(E2) ratios of all the nuclei. The
predictions of some energy levels are made using these models which may also be useful for theexperiments. We also use Talys and EXFOR data to understand the structure of nuclei.

University for financial support and hospitality during postdoctoral research at Meme Media
Laboratory, Hokkaido University Sapporo, Japan. The author is also thankful to Professor K. Katoand Professor S. Ganesan for constant encouragement and support.

2189-10 Collaboration between Nuclear Research Center,
NationalUniversity of Mongolia and Nuclear Reaction
Data Centre, Hokkaido University
S. Davaa, M. Odsuren and G. Khuukhenkhuu(National University of Mongolia, Mongolia㸧
Cooperation of the two centers (Nuclear Research Center (NRC), the National University ofMongolia (NUM) and Nuclear Reaction Data Centre (JCPRG), Hokkaido University) was started
since 2008 when Prof. Kiyoshi Kato from the JCPRG and Theoretical Nuclear Physics laboratory of
Hokkaido University, Japan visited NRC, NUM, Mongolia. Moreover, the NRC, NUM signed a
Memorandum of Understanding in 2010 with the Faculty of Science, Hokkaido University.
According to the Memorandum of Understanding, two centers have interest to exchange of faculty
members and research fellows, exchange of academic materials, publications and information,
conducting joint research projects and organizing symposiums.
We should point out that the JCPRG makes important contributions in the nuclear research in
Asia and serves to create the Asian nuclear data centre as like European nuclear data center. The
JCPRG has partnered with Asian research centres and welcomes more partnerships for othercountries. Researchers from the NRC have been compiling at the JCPRG the experimental dataobtained in Japan for the charged particle induced and photonuclear reactions for the EXFOR
library and evaluation of nuclear reactions and scattering cross sections.
In the framework of the R&D Platform Formation of Nuclear Reaction Data in Asian Countries/2010-2013/ supported by Japan Society for the Promotion and Science (JSPS) the Asian nuclear
reaction database development workshops were organized by the JCPRG. The workshops were held
every year: Sapporo (2010), Beijing (2011), Pohang (2012) and Almaty (2013). Mongolian
researchers were participated above mentioned workshops.
In 2012 Prof. S. Davaa and Prof. G. Khuukhenkhuu visited the Theoretical Nuclear Physics
laboratory, Hokkaido University. We had presentation on the recent research results at the NRC,
NUM, Mongolia and discussed with Prof. K. Kato and Prof. M. Aikawa about future collaborations
between NRC and JCPRG. Prof. M. Aikawa, Dr. A. Makinaga visited Mongolia and participated inthe 3rd International Ulaanbaatar Conference on Nuclear Physics and Application UBC2012, 17-20
September 2012. In addition, Prof. K. Kato participated in the International Conference on
Contemporary Physics, ICCP-V, from 3 to 6 June, 2013, Ulaanbaatar, Mongolia and had talk on the
scattering problems for the complex scaling method.
Dr. M.Odsuren is currently a researcher at the NRC, NUM. For the last three years(FY2011/4-FY2014/3) she had worked at the JCPRG as a postdoctoral researcher. Her research has
focused on scattering problems for light nucleus using the complex scaling method (CSM) and theextended completeness relation (ECR). In collaboration with her co-workers, she considered aformalism in the scattering theory based on the complex scaling method with appropriate L2-basis
functions. In their work, a complex scaled Green’s function has been introduced to obtain the
response functions as observables. A novel method for calculations of the scattering phase shifts inthe light nuclear systems was proposed using this method and the decomposition of scattering phase219

shifts into resonances and continuum states was calculated. In this work the explicit relation
between the scattering phase shifts and the complex-energy eigenvalues in the CSM via thecontinuum level density (CLD) was obtained.
It is shown that the decomposition of the phase shift is useful for understanding the roles ofresonant and non-resonant continuum states. The phase shifts by using the typical potential withmany resonances near the real energy were calculated. Also, several realistic systems were analyzed
and compared with the observed experimental data. Theoretical study of decomposed scattering
phase shifts into resonance and continuum terms for realistic systems, a new concept of thedecomposition scattering phase shifts and decomposition of a cross section in few-body systems
were introduced. The new method can be used broadly for various systems which have different
characters. Finally, the decomposed cross section was calculated for the unbound states of
two-cluster systems.
In 2009, our young researcher Ms. D. Ichinkhorloo went to Theoretical Nuclear Physics
laboratory, Hokkaido University as a graduate student and in 2012 she defended her doctoral degree
and nowadays she is working at the JCPRG as a postdoctoral researcher. Her research field is thetheoretical evaluation of cross sections on the 6,7Li + n elastic and inelastic scattering, angular
distributions and neutron spectra. She applied the continuum-discretized coupled-channel (CDCC)
method for D + d and D + t cluster systems. In this analysis, total cross sections for the 6,7Li + nreactions by using the CDCC with the microscopic Jeukenne-Lejeune-Mahaux effective
nucleon-nucleon (JLM) interaction for incident energies between 5 and 150 MeV have been
calculated. It was found that the required normalization factor O w is larger, O w | 1.0 of 30 to 150
MeV from the analyses of the total cross section. The calculated total cross sections for 6,7Li + nreactions are good agreement with the observed data. Also integrated inelastic scattering crosssections for 4.652 MeV of 7Li in incident energies between 5-24 MeV were calculated. The
calculated data can be reproduced with O w | 0.1 in larger than 14 MeV and without imaginary partin less than 14 MeV of the JLM interaction, respectively.
The NRC plans to continue and to develop following collaboration with JCPRG in future:x To continue evaluation of the nuclear reactions data.
x To seek a possiblity for mutual study of gamma-ray induced reactions on the electron
accelerators: Microtron MT-22 at the NRC, NUM and Linac at Hokkaido University.
x To compile the experimental data from published article in the EXFOR library.
We are thankful for the financial support offered by the R&D Platform Formation of Nuclear
Reaction Data in Asian Countries (2010–2013), JSPS AA Science Platform Program to participate
in the Asian nuclear reaction database development workshops. We think that such workshops arevery useful to extend our international co-operation with Asian countries. One of the authors, M.O.,
is thankful for the hospitality and possibility to work for 3 years as postdoctoral researcher at the
JCPRG and Theoretical Nuclear Physics Laboratory of Hokkaido University.
